Tianxing, recently advanced packaging suddenly became popular, what is the reason?
We know that in order to block our advanced process, we can't get lithography machines below 14NM, which means that we can only rely on imports of high-end chips on mobile phones, computers and servers, and Huawei is even more miserable, even the road to import has been blocked, which has caused Huawei's mobile phone sales to plummet in recent years.
BUT THE REVERSAL OF THE PLOT IS COMING, HUAWEI SUDDENLY ANNOUNCED THIS YEAR THAT IT HAS SUCCESSFULLY MADE A 7NM CHIP WITH CONSIDERABLE PERFORMANCE, WHICH IS CONFUSING, THE WHOLE WORLD IS GUESSING, AND FINALLY IN THE RECENT DAYLIGHT.
It turns out that Huawei has adopted advanced packaging methods, bypassing the blockade of lithography machines, we know that in order to improve the performance of the chip, we must continue to add transistors on it, add more, the chip will become larger, in order to keep the chip smaller, we can only make the loaded transistors smaller, so there are 7NM, 5NM and even 1NM, but 1NM is the limit, and the cost is getting higher and higher.
This kind of lithography machine is needed to make the transistor smaller to be installed on the chip, because in order to solve the problem of the blank of advanced lithography machine, a new technology has emerged, that is, through stacking technology, a variety of chips are sealed together, such as analog, optoelectronics, sensing, etc. integrated in a system, due to the improvement of the synergistic efficiency of sealing on a substrate, the overall performance can also reach the performance of a single 7nm chip, and finally achieve the purpose of breaking through the blockade.
This is Huawei's current unique secrets, advanced packaging, which is the key to the rise of our science and technology, then the imagination space of Huawei chips in the future will be opened, from the original tens of thousands of chips to next year's 100 million and then hundreds of millions in the future, he is not only Huawei's rebirth, but also a major breakthrough in China's science and technology, so this plate is worth your good study.
