Samsung faces a very serious problem to surpass TSMC with its 2nm chips: the 60% curse

When semiconductor manufacturers produce a chip wafer, some of those cores do not function properly. It’s normal. When they start a new lithographic node your performance per wafer usually has a wide room for improvementbut little by little, as engineers refine their integration processes, this parameter improves. A mature lithography can deliver very high performance to IC manufacturers, but a nascent technology can move in the orbit of 50% performance.

Importantly, chipmakers need the per-wafer yield to be at least 60% to ensure node profitability and attract more customers. However, this figure is the minimum admissible. And in reality it must be much higher to optimize the competitiveness of photolithography from a commercial point of view. Currently TSMC and Samsung are manufacturing 2nm chipsbut according to the leaks the performance per wafer of its nodes is very different. And the South Korean company needs its 2nm node to be a success.

The 1 and 2 nm nodes are crucial in the itinerary that Samsung has planned

This reflection that Han Jong-hee, co-CEO of Samsung, made in mid-2025 express clearly At what point were you then? the largest company in South Korea: “First of all, I sincerely apologize that our stock performance has not met your expectations. Over the past year, our company has not responded appropriately to the rapidly evolving AI semiconductor market.” These words were addressed to his investors.

A very important idea emerges from Jong-hee’s words: the competitiveness of your subsidiary specialized in the manufacturing of integrated circuits is essential for Samsung. Even so, problems were arising from several fronts. “Our technological advantage has been compromised in all of our businesses. It is difficult to see that efforts are being made to drive great innovations or take on new challenges. There are only attempts to maintain the status quo instead of generating disruptive changes,” said an internal statement written by Jay Y. Lee, the company’s president.

In this scenario, Samsung needs its current best chip manufacturing technology, 2nm lithography, to be a success. And it’s in it. Integrated circuit producers do not typically make the per-wafer yield of their cutting-edge lithographs public, especially if it is relatively low. However, according to DigiTimes Asia Currently the performance of its 2nm nodes oscillates around 55%, so it is below the 60% threshold that we talked about a few lines above.

For this company, it is essential to increase the yield per wafer of its 2nm lithography because with a yield of 55% the percentage of usable chips after advanced packaging probably ranges around 40%. To curl the curl, again according to DigiTimes Asiathe per-wafer performance of TSMC’s 2nm nodes ranges between 60 and 70%which places this Taiwanese company, which is Samsung’s biggest competitor and the leader of the chip manufacturing industryin a very favorable position when it comes to attracting new clients. If Samsung manages to raise the performance of its 2nm nodes above 60% during the coming months, it will put up a fight against TSMC. Otherwise you will suffer.
