Breaking the monopoly of foreign countries, China taking a key technology of "core making"

"PM2.5" is a familiar tiny particle which is less than or equal to 2.5 microns in diameter. But we developed the key material of this manufacturing chip, and if you enter the PM1.0 dust in the process, the material is a waste, and it can't be applied to the chip. " In a simple sentence, Tang Yilin told a new core material, "ultra pure" and "ultra - uniform" - "photoresist with linear phenolic resin" for the harsh environment. In the early May, the steer of the largest phenolic resin production base in Asia told the science and Technology Daily that it took 26 years to develop domestic high-end electronic resins for chip production. Experts believe that this high-end material has broken the monopoly of the United States and Japan, and can greatly accelerate the development of China's autonomous chip. The success of "photoresist with linear phenolic resin" has made several photoresist enterprises ("chip" upstream enterprises) come to the top of the "core" materials, the science and Technology Daily reporter learned.

After 26 years of exploration, the key material of "core making" has finally been sharpening. Tang Yilin said: "the reason why we can develop and succeed is that the scientific research team has an endurance without breaking through and never looking back. This can provide some reference for Chinese chip research with heavy responsibilities. "
