Japan is reconquesting at full speed the chips industry. He has just manufactured his first 2 nm transistor

July 18, 2025 by usatoday24

Rapidus corporation It has just officialized A very important achievement: it has successfully manufactured its first 2 nm transist. It is very unusual for a company based just three years ago already stepping on the heels to the three giants of the semiconductor production industry: TSMC, Intel and Samsung. These companies plan to start Large scale manufacturing of 2 nm chips During the second semester of 2025, and, although Rapidus is not yet ready to manufacture this type of integrated circuits, the speed with which it is reaching intimidated milestones. This last company is with Tokyo Electron and JSR Corporation the best option in Japan for recover relevance which he had in the semiconductor industry in the 80 They monopolized in 1988 Nothing less than 50% of the chips industry. However, today none of these companies is positioned among the leaders of a sector dominated with iron fist by Taiwanese, American, Chinese, South Korean and German companies. Rapidus is fulfilling its promises one by one The latest generation semiconductor production plant that this company has put up in northern Japan, in the city of Chitose (Hokkaido), started the wafer processing tests in a pilot line. The directive plan of this factory is to start large -scale production of 2 Nm semiconductors in 2027, and is perfectly credible. In fact, the milestone that has just announced invites us to anticipate that they could even manufacture these chips massively before the end of 2026, although it is only a conjecture. Rapidus is a very young company. It was founded on August 10, 2022 by the Japanese government with an initial capital of 7,346 million yen (Something less than 46 million euros) contributed by, and here comes the interesting, Sony, Toyota, Nec, Softbank, Kioxia, Denso, Nippon Telegraph and MUFG Bank. The initial capital invested in the constitution of this company is not very bulky, but there is no doubt that the companies that participate in it They have an indisputable relevance in the sectors of technology, automotive and telecommunications. The purpose of Rapidus is to tune an automated production line that will be specialized in the manufacture of 2 Nm chips for AI applications The relevance of this organization, in any case, lies in the role entrusted to him by the government currently led by Shigeru ishiba. And, as I mentioned a few lines above, this is the company with which Japan aspires to recover competitiveness in the semiconductor manufacturing industry that had three decades ago. Its economy is at stake. In fact, this Asian country began to deploy its strategy to reinforce its integrated circuit industry more than two years ago, so the first results begin to see the light. What is causing the new Rapidus factory to monopolize the looks of the semiconductor sector is that, According to Atsuyoshi Koikewhich is the president of the company, will be completely automated. Its purpose is to resort to robots and artificial intelligence (AI) to set up An automated production line which will be specialized in the manufacture of 2 Nm chips for AI applications. Its plan consists, in short, to produce integrated circuits faster, with a lower and more quality cost. To manufacture these semiconductors, equipment of extreme ultraviolet lithography (UVE) produced by the Dutch company ASML, and practically all manufacturing processes are automatic. However, the tests of test and validation, interconnection and packaging of the chips are still largely carried out manually in most manufacturing plants. According to Rapidus, its automation technology of all these processes will allow you to reduce the delivery time of your chips by 66% compared to the times they usually offer TSMC and Samsung.

the fastest and most efficient transistor that exists

March 13, 2025 by usatoday24

Transistors are the cornerstone of Integrated circuits. The first as we know them were currently invented in 1947 by John Bardeen, William Shockley and Walter Brattain, three physicists from Bell laboratories. A simple way to define a transistor invites us to describe it as A semiconductor electronic device which is capable of responding to an input signal by giving us a certain exit. An electronic amplifier, for example, will increase the power, voltage or the current of the signal that we place at its input, using an external power supply. There are several types of transistors (bipolar, specific contact, field effect, uniunion, unique electron, phototransistors, organic electrochemicals, etc.), but, fortunately, we do not need to deepen them much more to be able to move forward with this article. It is enough for us to know two more data about these devices. On the one hand, what They are active elements within the integrated circuits. And, in addition, that those that have allowed us to achieve the level of integration used by current lithographic techniques are those of field effect (FET). Bismuth transistors promise us to change the rules of the game of chips The Spanish physicist Pablo Jarillo-Herrero and his MIT colleagues (Massachusetts Technology Institute), in the US, they talked about the potential of Boro Nituro in a scientific article that they published in Science In 2021. At that time his proposal was only theoretical, but three years later They brought their ideas to practice. And yes, they have enormous potential. What they did, in short, is to manufacture a new type of transistors using an ultra -elapsed ferroelectric material constituted of boron nitride (it is an extremely hard compound formed in the same proportion by boron and nitrogen). This Chinese transistor is 40% faster and 10% more efficient than the most advanced Finfet transistors of Intel and TSMC The starting point of the researchers of the University of Beijing we are talking about in the head of this article is different. In the scientific text they have published in Nature Materials They argue to have designed A GAAFET type field effect transistor (Gate-Lall-Around Field-Effect Transistor) that is 40% faster and 10% more efficient from an energy point of view than the most advanced finger transistors that use Intel and TSMC today. Sounds good. GaaFet technology is already The present of the semiconductorsso TSMC, Intel and Samsung have been working on it for several years. However, these Chinese transistors have a characteristic that clearly unchecks them from the devices that are using the three companies I just mentioned: they use bismuth instead of silicon. The use of this chemical element, according to these Chinese scientists, allows these transistors to solve the limitations imposed by silicon when implementing integrated circuits that They go beyond the 3 nm. These statements by Peng Hailin, Professor of Physical Chemistry at the University of Beijing and leader of this research, express with roundness Why these transistors are important: “It is the fastest and most efficient transistor ever created (…) If innovations in chips based on existing materials are considered a shortcut, then our transistors based on 2D materials are like ‘changing lane’ (…) Our research shows that the GaaFet 2D exhibits a performance and energy efficiency comparable to silicon commercial transistors, which makes them promising candidates for The next generation of semiconductors“Hopefully it is like that. I hope these transistors succeed when leaving the laboratory and be adopted by the industry. Image | TSMC More information | Nature Materials In Xataka | Cobalt is one of the most coveted metals.
