Academicians of the Chinese Academy of Sciences suddenly announced that without relying on TSMC, domestic chips can still overtake

as the "lifeline" of the global science and technology industry, semiconductor chips have been developed in China for a long time, and cutting-edge technologies such as lithography have always been in the hands of European and American countries. There are no high-precision lithography products, so domestic high-end chip products can only be produced by external OEM

Huawei Kirin's chip shutdown undoubtedly reminds more technology enterprises to avoid being "stuck" by chips. Huawei has launched its own "plan" and plans to design and manufacture the first chip manufacturing industry chain this year to get rid of technology dependence

at present, almost all high-end chip products in the world are inseparable from the chip OEM technology of TSMC and Samsung, but these enterprises use a large number of US patents in their production

it is difficult for China to break through the relevant technological blockade. Without its own high-end semiconductor industry, it can only develop in limited places

but recently, academicians of the Chinese Academy of Sciences suddenly announced a news, and pointed out that there is no need to count on TSMC, and domestic chips can still be surpassed. In China, including Peking University, Tsinghua University and other domestic first-class universities, more than 170 universities and research institutions have held "seminars on materials and information devices" in Xiangtan and Hunan, At the meeting, academician penglianmao introduced the difficulties currently faced by the most easily damaged equipment in the rotating friction of China's semiconductor industry, including the damage testing machine, and said that "China still lacks core technology and independent research and development capability in the field of chip technology."

due to the blockade of Western technology, it is difficult for China to make a breakthrough on the original basis. However, academician penglianmao also pointed out that carbon based semiconductor technology has brought the possibility of "direct pursuit" to China. So what is carbon based semiconductor

at present, most of the chip raw materials in the market are silicon-based materials. Silicon chips have gone through more than ten processes, such as wet cleaning, photolithography, ion implantation, etching, etc. Photolithography processes the designed circuit model on silicon wafer

however, due to material properties and lithography technology, chip manufacturing is behind 3nm. Traditional silicon wafer materials have some limitations. In order to break this limitation, a new material technology carbon based semiconductor is proposed

Jane but the main matters needing attention will be carefully inspected in Orlando, Florida. In terms of this technology (Booth No. s28196) exhibited at npe2015 exhibition, Moore's law is coming to an end, and the most likely substitute for silicon-based materials is carbon based materials. The advantage of carbon based materials is that the materials are brand-new, and other links are different from the design of silicon chip materials, so the brand-new industrial chain means brand-new opportunities

different from the development time of silicon-based semiconductors, China does not lag behind developed countries in the research of carbon based semiconductor technology. After the chip manufacturing process breaks through 3 nm, the wafer materials used may be replaced by this new material

this is also an opportunity for the development of the domestic semiconductor industry. Previously, amsl in the Netherlands insisted on developing EUV process and became the world's largest lithography machine supplier. Now, although carbon based materials are still in their infancy, it also brings hope of catching up with and surpassing the domestic semiconductor industry
