bypasses ASML, Huawei reveals a solution to the chip
The photolithography machine is an essential equipment for manufacturing chips.
ASML is the most advanced lithography machine in the world. Its DUV lithography machine and EUV lithography machine have occupied the mid-range, mid-range and high-end markets.
However, due to changes in chip and other regulations, manufacturers such as TSMC and ASML are unable to ship freely.
HiSilicon chips are produced by TSMC, and TSMC cannot supply them at will.
ASML cannot be exported at will, and it is difficult for Huawei itself to use ASML equipment to build its own factories.
my country has developed a new photolithography technology
Recently, domestic semiconductor company Xinlian Technology announced the launch of 3D 4f DRAM architecture technology based on Hitoc technology. Through this technology, DRAM chips can be produced without using a photolithography machine, and multiple pattern exposure SAQP steps are not required, which can greatly reduce costs. This is undoubtedly exciting news for my country's semiconductor industry.
In addition, the Japanese company Kioxia has also teamed up with Canon to develop a new NIL (Nano Imprint Lithography) technology, which can produce up to 5nm chips without the use of EUV lithography machines. Currently, Kioxia has Master 15nm mass production technology.
can see that under pressure from the United States, some countries are accelerating the development of chip processes and equipment to reduce their dependence on ASML lithography machines. ASML’s position in semiconductors is in jeopardy.
SMIC previously spent 1 billion to purchase an EUV lithography machine from ASML in order to support the development of the domestic semiconductor industry. However, in the past three years, this lithography machine has still not been implemented in our country.
Faced with this situation, Huawei can only solve this problem by itself. It actively independently researches Chinese chips, and provides strong support to domestic chip supply companies, encouraging other technology teams and R&D organizations to join in chip manufacturing. even proposed that the chip’s autonomy should reach 70% by 2025.
This move can be said to be a nationwide effort to promote Chinese chip research. Fortunately, Huawei’s strength cannot be underestimated. In the first four months of this year, China’s chip imports decreased by 24 billion. can be said to be proud and proud, having completed most of its goals three years in advance.
In addition, many local chip companies in China are also getting good news frequently, and some chip foundries are also on the right track of rapid development with the rise of domestic chips. Therefore, it only takes one year to change American chips from "unavailable to buy" to "unsellable".
