In the field of chips, China has also heard a lot of good news recently. In recent years, there have been many voices in China asking the country to develop its own chips, but the process of researching chips and the technical fields of design are very complicated, which is why We would rather spend such a large price every year to find the reason why other people's foundry chips.
But in recent years, Chinese chips have also reached the point of irreversibility, especially the US's chip sanctions on China, which made us realize that the production of Chinese own chips is not only a technological issue, but also China’s future. The problem is that some time ago the Chinese Academy of Sciences also suddenly announced that in the field of chips, the Chinese have achieved "changing lanes and overtaking."
We all know that the semiconductor field is still based on silicon-based semiconductors as the main material. The manufacture of such chips is very dependent on the Dutch EUV lithography machine. We have always wanted to get the Dutch EUV lithography machine, but we are helpless in the United States. China has tried all the methods to achieve little effect. At most, it can only obtain DUV lithography machines.
DUV lithography machine seems to be a high price and low configuration at present, and compared with EUV, DUV requires multiple exposures. The cost of each exposure is greatly increased, and the subsequent use cost is also very high. This is only It is a pity that we have not mastered the technology in this area. If the Chinese have mastered the lithography machine technology by themselves, I believe that not only DUV, even EUV lithography machine, we can also make it into "cabbage price."
is also due to this dilemma. China has not used its brains in the field of lithography machines. If this method does not work, we will change it. Graphene is a new trend in the semiconductor field. China has been in this field since 2009. Research has been carried out, and some time ago, the Chinese Academy of Sciences also announced the news of a major breakthrough in graphene 8-inch wafers. On the chip road, the Chinese have also made different achievements.
And because other countries have not invested too much research and development in the graphene field, China currently occupies the world's leading position in the graphene field. In the future, graphene-based carbon-based chips are the major trend. We are now It may be in a dilemma that is difficult to break, but from a long-term perspective, China is likely to realize "changing lanes and overtaking" and completely get rid of silicon-based dependence.
