TSMC recently said that after September of 14, TSMC will no longer be able to provide chips for Huawei mobile phones. Who is this TSMC? Why did they stop supplying chips to Huawei? Why should Huawei's chips be produced by TSMC? Understand the logic of these questions, and everyone will understand where the pain points of "coreless" domestic mobile phones are.
The core part of our mobile phone is the chip, which determines the performance of a mobile phone. Smartphones usually have about 20 chips. There are four main steps in the chip manufacturing process: design, manufacturing, packaging and testing. In China, the technology of chip packaging and testing has matured, and there are also top companies like Hisilicon in design. However, the manufacture of chips is our technical shortcoming, and we can even say that there is still a big gap between us and the United States in this respect. TSMC is a Taiwan Province company that produces chips for Huawei. It is not that TSMC is unwilling to produce chips for Huawei, but that the technology and software used by TSMC to produce chips were invented by Americans, and the patents are in the hands of Americans. Therefore, under the pressure of the United States, TSMC cannot continue to undertake Huawei's chip production business.
Someone must want to ask, is a small chip really that difficult? Our manufacturing industry in China is so powerful that we can't produce a single chip? Sadly, we really can't produce it at present. Why is this happening? Then we need to know the main technical difficulties in chip production. The first step is to refine high-purity silicon and make it as thin as possible. Then we will use high-end mask aligner to print fine patterns on the silicon wafer, and then we will put hundreds of millions of transistor elements on it and finally package it. The accuracy of this operation is 7 nanometers. What is the concept of 7 nanometers? It is one tenth of the diameter of a strand of your hair, and on this basis, it needs complicated processing, so the accuracy of calculation can reach one tenth of that of your strand of hair. You know how hard it is! If you enlarge a chip by 10,000 times, it seems that there are many overpasses and highways on it.
The most important equipment is the mask aligner. At present, the precision of mask aligner produced in China is not high, which can not meet the manufacturing requirements of high-end chips. The highest accuracy of mask aligner in the world is ASML in the Netherlands, so some people say that it is not American. Sorry, the shareholders of this Dutch ASML company are Intel Corporation and TSMC Corporation in the United States. If Huawei can have such an accurate mask aligner, it is estimated that there would be no TSMC!
Now that the United States has ordered it, it has seized the "throat" of domestic mobile phones. A small chip has become the biggest pain in the domestic mobile phone manufacturing industry, and it has also become a major event in the hearts of Chinese people. Facing the fierce attack of the enemy, we have no way to escape. If you are weak and resigned to your fate, you can only be completely defeated. As Ren said, without scars, where can you get rough skin? Heroes have suffered more since ancient times! Sanctions are painful, but in the eyes of the brave, they are also full of opportunities.
Have we ever been afraid of depression? Did you completely collapse in the suppression? Recently, I began to make efforts in the chip manufacturing industry, investing money and attracting talents. We are already on the move! Ren personally visited colleges and universities in order to enable Huawei to design, produce, package and test the whole chip industry chain and have the ability to complete production independently. A big country is a heavy weapon, and we must master it ourselves. A blessing in disguise is a blessing in disguise. Chinese sons and daughters are ready to rest on their laurels and embark on the most tragic long March in the history of science and technology! We are glad to see that under the current tense situation between China and the United States, more and more overseas talents have given up their annual salary of millions of dollars abroad and returned to the team of building the motherland. After all, we have been making wedding dresses for others for too many years! I believe that even if there are thousands of difficulties and dangers in front of us, we will certainly be able to tide over the difficulties! Looking back on the past, going forward bumpy and never giving up! Every man is responsible for the rise and fall of the country, and we must constantly strive for self-improvement!
