Hello, I’m Mr. Chen. Recently, our country’s science and technology circle has been bustling with activity, and one topic has attracted a lot of attention. Guess what? Former TSMC R&D Director Yang Guanglei’s comments on Chinese lithography. He said ah, Chinese lithography to do 8nm technology is absolutely possible, but how much yield is still a question mark. These words, can really make people excited and apprehensive ah!
Do you know what a photolithography machine is? Simply put, it’s like a magic pen for the chip drawing, determining the precision and performance of the chip. Our country has always been a little behind in this area, by other people’s neck. But now there is good news! Our domestic 65nm argon fluoride lithography actually achieved 193nm wavelength output, which is a big breakthrough ah!
Yang Guanglei, who has worked at TSMC for many years, knows chip manufacturing like the back of his hand. He said that our photolithography machine can theoretically handle 8nm chips, which made a lot of people excited. Some students may ask whether we can immediately use the domestic high-end chips? Hey, don’t be anxious, Chen has to throw some cold water.
Although technically feasible, but the yield rate of this hurdle can not be passed. What is the yield rate? It is the production of the chip, can be used in what proportion. Imported foreign photolithography can reach a yield rate of more than 90%, but we are only about 70-80%. This is just like your exam, knowledge points are mastered, but do the questions always wrong, the final score can not go, what a pity!
But don’t be discouraged, students. Our country’s science and technology workers have a lot of energy. Take TSMC for example, they also started as a chaser. Yang Guanglei said that the closest TSMC came to Intel was in the 14nm process. You see, now they have mass produced 5nm chips, Intel’s 7nm process has just been put into production not long ago. This is not a living example? As long as we work hard, we will be able to catch up!
Speaking of which, I remember an interesting thing. Do you know who the world’s largest lithography manufacturer is? It’s the Dutch company Asmac. This company’s position in the field of photolithography is even more powerful than Intel’s in the field of chips. But they’re getting nervous now. Why? Because China’s lithography technology is advancing too fast! Although only 28nm, but from scratch this is progress.
Sources say that Asmac’s president immediately asked his staff to work on the progress of our domestic lithography when he learned about it. They also plan to cooperate with us in the production of 28nm chips. What does this mean? It shows that our technology has attracted the attention of international giants! Students, this is not very exciting?
But Chen has to remind you that technological development can’t be achieved overnight. Just like your studies, you can not only look at the test scores, but also focus on the accumulation and application of knowledge. Although our lithography technology has made a breakthrough, there are still a lot of challenges in terms of yield rate, cost control, production stability and so on. This requires us to continue to work hard and continue to explore and innovate.
Students, what do you think about the future of domestic photolithography? Can we get rid of the neck of the dilemma as soon as possible? You are welcome to leave your comments below and tell us what you think. Remember, when technology is strong, the country is strong, and you are the future hope of the motherland! Study hard and contribute to the development of science and technology in the future.
Finally, I would like to say a few more words. Learning scientific and technological knowledge is important, but more important is to cultivate scientific spirit and innovative thinking. You should learn to think independently, the courage to question, dare to try. Maybe one day, one of you will become the next Yang Guanglei, and make significant contributions to the development of science and technology for the country! Go for it, classmates!
