Three years ago, the United States banned the supply of Huawei chips for spurious "reasons", resulting in the dilemma of using one less HiSilicon chip. Time has passed, and the hysterical suppression of the United States will only be to move stones and drop feet.
It is heartening that Huawei recently announced a major breakthrough in the field of quantum chips, and I believe that in the near future, it will be able to completely get rid of the restrictions of foreign chip shackles.
It is true that the domestic industry started late, so that some Western countries have the opportunity to rely on technological advantages to put China in an unequal position, what is less known is that in the field of chip manufacturing, we still have our own pride, in the early years, domestic companies will be a 20 million yuan price to export to foreign enterprises, not a penny less, it is an etching machine.
The birth of the chip
As we all know, the importance of lithography machine to chip production is beyond doubt, can be carved on the silicon chip circuit diagram, but the chip texture is extremely fine, how to remove excess silicon material without damaging the circuit diagram under the premise of becoming another key technology in chip production, etching machine is such a little bit of "cut" out.
Lithography machine and etching machine are indispensable for the generation of chips, and their production process is extremely complex, marking the level of national science and technology.
In the field of lithography machine, we have not made great achievements, but in the field of etching machines, domestic enterprises have long led the world.
Not only has it independently developed a world-leading etching machine, each priced at more than 20 million, but it is still snapped up by European and American companies such as Samsung for the production of 5nm chips, which is really a competition.
Nowadays, the technology of the domestic etching machine is enough to be proud of the world, but its research and development still has a sad past.
The story of the etching machine
Speaking of etching machines, Yin Zhiyao, the father of domestic etching machines, deserves our respect and attention.
Yin Zhiyao, who has been smart since childhood, has studied exceptionally well, so he has also been given the opportunity to study in the United States. During his studies in the United States, he deeply realized the gap between China and the United States, especially the unreasonable technological blockade of China by the United States, which made him determined to return to China to develop.
After a long study in the United States, Yin Zhiyao mastered many advanced chip technologies, and became the most accomplished Chinese in Silicon Valley with more than 400 patents, when he was 60 years old, he gave up his high salary and resolutely chose to return to China, according to incomplete statistics, he did not return to China alone, but brought more than 15 elite teams, it is this team that has made great contributions to the early chip field in the mainland.
However, before Yin Zhiyao returned to China, he was obstructed by the M country layer by layer, not only withstood unreasonable censorship, but also deleted all his computer content, confiscated tens of thousands of design drawings, and Yin Zhiyao's half life's hard work was destroyed!
Yin Zhiyao returned to China after the establishment of Zhongwei Semiconductor Company, under his unremitting efforts, to break through one technical difficulty after another, etching machine production process is more and more mature, in recent years, Yin Zhiyao team has successfully developed a 12-inch etching machine, and applied to TSMC 5nm chip production, and successively obtained global technology patents, leading the domestic etching machine field to stand at the top of the world.
For the gap in the mainland semiconductor industry, Yin Zhiyao once frankly said, "It takes 5-10 years to catch up time", in order to narrow the technology gap, 77-year-old Yin Zhiyao is still struggling in the front line, which is really admirable!
brief summary
The years are quiet, it is someone who carries the weight forward.
Yin Zhiyao walked on the red carpet
From the technological breakthrough of Huawei's quantum chip to the global leadership of the etching machine, the domestic strength is no longer what it used to be, and I believe that with the efforts of more experts like Yin Zhiyao, we will break through the layers of blockade and reverse the situation.
