As we all know, the manufacturing process of the chip is very complicated. First, we have to dissolve the grains of sand, extract the silicon wafers, and then cut them into thin silicon wafers. After photoetching, etching, plasma implantation, sealing and testing, etc., they can be applied to various electronic products.
China entered the semiconductor industry late, and there is a certain gap in technology accumulation between China and western developed countries. This is a problem that we must face squarely. However, in order to limit the development of China's science and technology, those western countries that have mastered the core technologies of semiconductors signed the Wassenberg Agreement decades ago, prohibiting the export of all core technologies to China, which forced Chinese science and technology enterprises to rely on imported chips.
after the United States cut off the source of Huawei chips, Ren Zhengfei said in an interview with the media that the main reason why China enterprises could not manufacture high-end chips by themselves was that the equipment for manufacturing high-end chips was stuck in the neck. Therefore, in order to realize the localization of high-end chips, we must develop mask aligner, etching machine and other equipment.
in order to promote the development of the domestic semiconductor industry, the state has issued a large number of preferential policies for the semiconductor industry, and established the first "chip university" in China, created the "Oriental Core Port" and put forward the slogan of "piercing the sky upwards and taking root downwards".
under the call of the state, enterprises, scientific research institutions and scientists in China started a wave of "core building" and made major breakthroughs, such as the domestic "practical" enterprise Shengmei Semiconductor conquering high-end chip equipment.
According to media reports, the domestic semiconductor giant Shengmei Semiconductor officially announced that it has successfully developed the edge wet etching equipment, and the core technology has been independently controlled, which has been verified by domestic manufacturers and will be delivered to downstream enterprises in the third quarter of this year.
It is understood that this edge wet etching equipment developed by Shengmei can remove all kinds of electrolyte, metal and particle pollutants at the edge of the wafer, reduce the influence of edge pollution on the subsequent process, and improve the yield, and the effect is much higher than that of the edge dry etching machine.
It is worth mentioning that the edge wet etching machine equipment market has been monopolized by American and Japanese enterprises, accounting for 95% of the market. Now, Shengmei has successfully developed the edge wet etching machine and equipment, which fills the gap in this field in China and further tears the technical wall of the West.
For China's continuous breakthrough in semiconductor equipment, American scholars expressed their feelings: It was a very stupid decision for the United States to suppress China enterprises such as Huawei. This move not only failed to curb the rise of China's science and technology, but also stimulated the blood and fighting spirit of China people and made them stronger!
As American scholars have said, China people are the smartest people in the world, but we are easy to be satisfied and slack, especially when we are rich, and it is easy to tell the difference between the east, the west, the north and the south. Otherwise, we will not say such things as "technology has no national boundaries" and "it is better to buy if it is built, and it is better to rent if it is bought".
The United States often finds fault with us and gives us trouble. It is a good thing for us. It can keep our minds awake at all times, make us stronger and lead the progress of human civilization!
I believe that as China scientists continue to break through the "bottleneck technology" and manufacture self-controlled semiconductor equipment, "China Core" will surely rise strongly, break the chip blockade in the United States and help domestic enterprises pick up the dignity of being rubbed by others!
