A giant is ready to get into the market of chips manufacturing machines: LG Electronics

by

The HBM memories market (High Bandwidth Memory) that work side by side with the GPUs for artificial intelligence (IA) Three companies lead it clearly: Samsung, SK Hynix and Micron Technology. Interestingly, memory chips are The South Korean economy engine Trade dependent. And Samsung and Sk Hynix are Companies that support this industry In this Asian country. In fact, these two South Korean companies compete with each other to master the lucrative HBM memory chips. AND They do not supply when it comes to manufacturing as many integrated circuits as their customers demand. The most important of all of them is, as we can intuit, Nvidia. The export of semiconductors in South Korea increases, but its chips stocks 33.7% fell in April of 2024 compared to the same period of 2023 according to the National Statistics Office. In any case, another South Korean company is ready to enter the market for integrated HBM memory circuits, although it will not compete with SK Hynix and Samsung. LG is preparing a unique machine to produce HBM memories Manufacturing integrated VAGUARD HBM circuits is not simple. The processes involved in the production of these chips are complex, and in them very advanced technologies are involved. SK Hynix, Samsung and Micron are manufacturing on a large scale, although with different success12 -layer HBM3E memories. The two South Korean firms will produce large -scale HBM4 chips during the second semester of 2025, and Micron will do so in 2026. However, CXMT (Changxin Memory Technologies), one of the Chinese companies specialized in the production of memoirs, will launch Your first HBM3E chips in 2027. The main quality of this equipment will be its ability to allow the stack of integrated circuits in a much more efficient way China has several memories manufacturers Important, but they currently do not have solutions capable of competing with the best of SK Hynix or Micron. This circumstance reminds us of how complex it is to manufacture latest generation HBM chips. LG Electronics is going to enter this marketbut you will not compete from you to you with memory chips manufacturers. The opposite; aspires to be your customers. Koo Kwang-Mo, the president of this company, has confirmed That its strategy is to participate in the hardware industry for AI, but it will make it marketing its own chips manufacturing equipment. In fact, LG is developing a machine that will be specifically designed to produce avant -garde HBM memories. According to this company, the main quality of this equipment will be its ability to allow the stack of integrated circuits in a much more efficient way than with the technologies currently available. In theory, the innovation in which LG engineers are working will contribute to the tuning of HBM memories of more capacity and with a lower heat dissipation index. LG plans go to make their HBM memories production team in 2028. The main manufacturers of these machines are the American company Applied Materials and the Dutch Besi, so these are The companies with which LG will compete If finally its memory semiconductor production machine comes to fruition. If so, it is likely that Samsung, SK Hynix and Micron are interested in their team, although it is also possible to apply materials or kiss forward to LG. In fact, SK Hynix and Samsung plan to introduce this technology this year. More information | Economic Seoul In Xataka | Chinese memory chips manufacturers are a nightmare for the US and South Korea.

“Chatbots are nothing more than Plagiar machines”

by

In 2021 the world had not yet learned about what was coming, but Emily Bender – linguist and professor at the University of Washington – was very clear. That was when he copied A famous study in which he described the existing AI models as “Stochastic parrots“That expression since then became one of the best ways to define the basic functioning of Chatgpt. And four years later this expert is reaffirmed in its position: it is a skeptic with arguments. Stochastic parrots. The fundamental idea of ​​his analogy was to compare the models that were then (among them GPT-3, precursor to the used in chatgpt) as stochastic parrots. The “parrots” is clear, since models basically repeat what they are told through training. The “stochastic”, a not so well -known term, refers to the fact that the LLM do not repeat deterministicly or fixedly, but probabilistically predicts what the following word is most likely in a sequence based on the context. Aren’t humans? Sam Altman picked up the glove a year later, when the expression was already known. He did it on December 4, 2022, four days after Chatgpt was released. He wanted to try to make us see that according to him the human beings were also stochastic parrots. In a sense we are: We learn language patterns And we repeat phrases that we hear in addition to predicting what comes next in a conversation. However, there are critical differences with AI models. We understand what we say, while the LLM no We have awareness and intentionality when we speak, we not only produce probable sequences We have abstract reasoning and we are able to adapt reason, generalize and correct our errors in a flexible way: our thought is not purely statistical Declared skeptics. Emily Bender has not changed his mind in all these years. In fact, he has just published his book, ‘The ai with‘(Something like’ The Timo of AI ‘) in which he precisely develops the arguments on which he bases his reserves and skepticism regarding artificial intelligence. In a recent interview With Financial TimesBender stressed that the chatbots of AIs are nothing more than “plagiarism machines” and that the great language models (LLMS) on which they are based “have been born as shit.” They have sold us a lie. This expert believes that generative companies have sold us a lie. His models, he says, They will not fulfill those promisesbut they will not end the human race, as some have wanted to warn. In spite of all the expectation generated, in their opinion the chatbots are bad in most tasks and even the best models of today still have something similar to intelligence. And of “reasoning”, nothing. The new modes of “reasoning” that raise models such as O1, O3 or Deepseek R1 They are another lie in his opinionand that statement that they understand the world makes no sense. We are “imagining a mind behind the texts (generated),” he explains, “but all that understanding comes from our side,” not that of AI. It is not intelligence, it is automation. Bender, who is currently 51 years old, spent his first academic years in Stanford and Berkeley, and ended up working as a teacher at the University of Washington, where it has specially seen in how computers model in human language. In his opinion, the artificial intelligence name itself is exaggerated – an old debate – and should simply be called automation. Chatbots controlled by power. In her book ‘The AI ​​with’ She and her co -author, Alex Hanna, warn of the danger of current AI models. Especially since they are controlled by large companies with certain interests. “Thanks to the huge sums invested, a tiny camera clique has the ability to influence what happens to great stripes of society, he explains. Too much Hype. And in front of Altman or Amodei’s speeches and promises, which promise that We will arrive at the AGI soon or that the AI ​​replace Millions of workersBender’s vision is much more skeptical. For her it is nothing more than a “beautiful wrapping for spreadsheets”, but there is neither magic nor an emerging mind. A magical 8 ball with pretensions. His skeptical vision goes against personalities such as Sam Altman or Elon Musk, who do not stop promising all kinds of revolutions. “That everyone believes that this (AI) is a thinking entity goes to your benefit And very powerful, “he explains,” instead of making people think that this is nothing more than a magic ball with pretensions, “pointing to this toy that agitas asking a question and answers you with a” yes “,” no “,” depends “or some more options.

A critical component of current chips manufacturing machines

by

The teams of extreme ultraviolet photolithography (UVE) that manufactures the Dutch company ASML are extraordinarily sophisticated. In fact, they are those currently using TSMC, Samsung, Intel, Sy Hynix and Micron Technology for produce integrated avant -garde circuits. They are so complex that during the first phases of their design in the early 90s of the last century, ASML engineers They believed it was impossible. However, everything changed in 1997. That year Jos Benschop, the leader of the research department, reassess whether UNVE technology was a viable option. After the first tests he realized that The German company Zeiss He was able to develop extraordinarily sophisticated mirrors that would be necessary to transport ultraviolet light. And he was not wrong. That was the real starting point of technology that has made it possible for our mobile phones and computers to have such advanced chips. Zeiss’s feat arrived in the 90s One of the most complex elements of UVE lithography machines is The ultraviolet light source. The company of American origin Cymer, although since 2013 it is not an independent company. That year ASML executives decided to buy it to accelerate the development of the technologies involved in UVE lithography. An interesting note: the ultraviolet light is responsible for transporting the geometric pattern described by the mask so that it can be transferred with a lot of precision to the surface of the silicon wafer. Understanding what is the mask is simple: it is nothing other than a physical template that contains the design of the integrated circuit that is necessary to transfer to the Silicon wafer. In any case, there is another component without whose intervention It is not possible to carry out this crucial task. Other components, in plural, in reality, although all of them are of the same type. It is precisely the mirrors that Jos Benschop suspected in 1997 that Zeiss could produce. The light of 11.4 nm was discarded because it forced to use beryllium in the mirrors and is a toxic chemical element The role of the optical elements of this company in these lithography equipment is crucial. And it is because they are responsible for moving the UVE light with a wavelength of 13.5 nm from the source that is responsible for its emission to the mask contained in the geometric pattern that is necessary to translate into the silicon wafer. If the mirrors involved in the propagation of the UVE light are not manufactured with enormous precision the geometric pattern defined by the mask will be altered, and the chips will be damaged. Interestingly, the choice of the wavelength of the UVE light used by these machines was a very delicate decision. Initially the engineers involved in their tuning had four possible options: 13.5 nm, 11.4 nm, 6.6 nm and 4.8 nm. These last two wavelengths were finally ruled out due to the limitations they imposed Organic photorestoning materials. The light of 11.4 Nm was also discarded because it forced to use beryllium in the mirrors, and is a toxic chemical element. The wavelength of 13.5 Nm required to introduce molybdenum and silicon mirrors, but these elements do not pose any problem. This is the reason why UVE machines work with this light. In any case, this data clearly reflects the extraordinary level of precision with which it is necessary to manufacture the mirrors: Zeiss uses argon ions and other elements to polish layer per layer at the atomic level the mirrors, and then identifies and corrects the defects using a subnustric analysis technique. This last tool is capable of detecting defects with a lower precision than a nanometer (less than a millmillonieth part of a meter). * Some price may have changed from the last review Image | Zeiss BIBLIOGRAPHY | ‘Focus: The Asml Way’by Marc Hijink More information | Zeiss | Asianometry In Xataka | 2024 has been a year full of uncertainty for chip designers.

More and more young in Spain turn to laser machines to erase tattoos

by

There are situations that are no longer forever, even if you record them with ink. Although a third of the young Spaniards carries at least one tattooa trend in social networks It is showing that it is increasingly common to erase what one day was permanent. The “forever.” That is one of the most common phrases when you get a tattoo: “Are you sure? It’s forever.” In recent years, tattoos have popularized so much that Spain occupies The sixth place in the world With more tattooed people, and any event It looks like a good idea. However, according to A study by Lutronic PBSManufacturer of medical-aesthetic laser devices, in our country 60% of the people who tattoo regret it. The most common profile in this trend are women between 35 and 50 years old. And it is not an isolated phenomenon: An American investigation Pew Research showed that one in four people regrets at least one of his tattoos. Examples. This is the case of Natalia, 35, who has asked not to reveal her real name. She decided to erase the micropigmentation eyebrows due to the misinformation about this treatment. When he made them, they told him that it would be semi -permanent, but in the end it turned out to be like a tattoo. As she herself, there is no harm that for good does not come: when looking for a center where to eliminate micropigmentation, she also took the opportunity to erase her first tattoo, which “had nothing to do with it.” The story of that first tattoo dates back to his 18 years: “He was too young, it was more as a impulse of rebellion,” he explained. Over the years, more tattoos were made, but he has assured that “it has nothing to do with my style.” It is easier to do so than eliminate it. “The tattoos ink is deposited in the dermis, the second layer of the skin, because its molecules are too large for the body to break down,” Expert Goergen explains CNN. Laser devices emit rapid energy pulses that fragment the ink into smaller particles, which the body processes through the lymphatic system. In safe hands. So it is essential to have a good professional when making a tattoo. In the case of Sara, 30, who also wants to preserve her identity, her tattoo was performed by a person who considers “a bit inexperienced.” He does not like how he looks or how the tattoo feels in his ankle: “In the background I feel sorry to erase it. I did it with 21 years with money that I had saved, but it is like bulky, as if I had not healed well.” Sara consulted with a dermatologist who told him that the ink could have crossed the surface layer of the skin and that it would be advisable to eliminate it as soon as it could. This situation resembles a Swedish preliminary study, conducted with 11,000 people, which suggests that those who have tattoos They have 21% more risk of developing lymphomas compared to those who do not understand it. A good team. It is important to keep in mind that the process of removing laser tattoos, such as Q-Switched, requires specialized training. Natalia was clear: he thoroughly investigated and specifically sought that team, considered one of the most effective for erase. According to the Spanish Society of Aesthetic Medicinethe incorrect use of these equipment, poorly regulated or applied by unprepared people, can cause serious adverse effects, such as burns or scars. In addition, the organization complaint work intrusion and lack of regulation in these cases and others of aesthetic medicine. How many sessions do you need? Although there are clinics that promise to eliminate a tattoo in a single session, experts from the IML Dermatological Clinic They have warned that this is only possible in very specific cases (very small, old tattoos, with black and shallow ink). The most common is to require several sessions, separated by weeks or months. And yet the process is not exempt from complications. The least visible of the process. Jayne Foo, Singapore financial consultant, is part of a growing tendency of Influencers that shares your experience with aesthetic clinics to show the “before and after.” In his account he explains that he has had open wounds, huge blisters and extreme itching. In his networks he confirms that it is not so simple since you have to take precautions and avoid the sun. In addition, she warns that many videos in networks can be misleading, since they show what is known as frosted effect, which seems to clarify the ink immediately, it is only a temporary reaction that lasts about 15 minutes. An explosion to reverse the ink. Under him Hashtag #Tattoremoval on Instagram and Tiktok, more and more people show their tattoo elimination process. The influencer Claudieta, with more than two million followers, He has confessed: “Never make a tattoo at a time that you are bad psychologically.” In this context, and recently, A fans account of the actress Amanda Bynes a video has uploaded how a tattoo of the face is being erased, adding to the Trend viral. In the end a tattoo is an choice of life. A study revealed that the most impulsive people tend to tattoo more. But, as the interviewees have told us, what hurts is not so much impulse, but the process of reverse. Be that as it may, decisions are free and there is always time to change. Sometimes, erasing a tattoo is not forgetting the past, but accepting that it is no longer part of the present. Image | The Dame and Jayne Foo Xataka | The tattoos were always among us. And the European kings gave a Japanese dragon on their arm

Within the most advanced chips manufacturing machines there is something incredible: small supernovae

by

Identifying a Supernova is an event that astronomers usually celebrate with enthusiasm. And it is not for less if we consider that they are One of the most violent events with which we can run into the cosmos. Knowing them better is very important because it can help us understand more precision How are the latest stages of The life of mass starsand also the mechanisms that explain how the material caused by stellar synthesis can lead to new star systems. The mathematical tools handled by astrophysics current nuclear fusion that take place in the nucleus of mass stars. During the stage known as the main sequence, stars obtain their energy from the fusion of hydrogen nuclei. As this chemical element is consumed, the star begins to produce helium nuclei, and, of course, its composition begins to evolve. During this process a huge amount of energy is released and the star is forced to continuously readjust to maintain hydrostatic balance, a phenomenon that is the result of the coexistence of two opposite forces capable of compensating. One of them is the gravitational contraction, which compresses the subject of the star, pressing it without rest. And the other is the radiation and gase pressure, which is the fruit of the ignition of the nuclear oven and tries to expand the star. The small supernovae of the extreme ultraviolet lithography equipment As we have anticipated from the holder, this article does not go only from Supernovas; It is also starred by the semiconductors. A priori we can intuit that these cosmic events and integrated circuits have nothing to do, but, curiously, they do have something in common. This is the reason why I found a good idea to start this text reviewing what a supernova is and why they occur. Otherwise we could not understand in all its extension the idea in which we are about to investigate. The ultraviolet radiation generation process used by UVE lithography equipment is very similar to what happens during a Supernova In the teams of extreme ultraviolet lithography (UVE) that manufactures the Dutch company ASML, high power lasers instantly heat tens of thousands of tiny tin drops in a single second until they reach a temperature of half a million Celsius degrees. This interaction produces An extremely hot plasma that emits ultraviolet light with a wavelength of 13.5 nm. This light must later be transported to the wafer thanks to a very precise mirrors and lenses system with the purpose of capturing the patterns that define the integrated circuits on a layer of photorers. Very broadly this is the strategy used by the most advanced semiconductor manufacturing machines that currently exist. And, as we have just seen, high -power lasers interpret an unquestionably protagonist role. As Jays Stewart, Chief of Research at ASML, explains in the very interesting article he has published in IEEE Spectrumthe ultraviolet radiation generation process used by UVE lithography equipment to produce avant -garde chips is very similar to what happens during a supernova. When a massive star exhausts its fuel and stops nuclear fusion processes, radiation pressure and gases is no longer able to counteract gravitational contraction. This phenomenon causes the star iron core It suddenly contracts under the enormous pressure that all layers of material that it has above. The star has lost the hydrostatic balance. At this moment all this matter loses the support that the nucleus exercised, which is now much more compact, and falls on it with enormous speed. When all that star material touches the surface of the nucleus there is a rebound effect that causes it to be fired with a huge energy towards the stellar medium, being disseminated. A supernova has just been produced. Some of them are so energetic that for a few seconds they emit more light than the entire galaxy that contains them. The tiny explosions that take place inside the UVE lithography equipment when a laser affects a tin drop produce a shock wave similar to that originating in the stellar medium, although much smaller scale. Surprisingly the mathematical equations that describe the evolution of these two types of explosions are the same. ASML engineers use them to calculate very precisely how the evolution of the shock wave that triggers plasma balls within the UVE equipment will be. And astrophysicians use them to describe the remains of the supernovas and deduce the properties of the star explosion that originated them. A Supernova has 10⁴⁵ times more energy That an explosion of tin, but thanks to this parallel, ASML engineers have been able to solve the complex problem derived from tin residues inside their most advanced lithography equipment.
