ASML’s EUV lithography machine is the only one in the world. Now it is mainly used in the logic process of 7Nm and below. TSMC and Samsung use it to produce CPU, GPU and other chips. Immediately memory chip will follow up, SK Hynix announced mass production of EUV process memory by the end of next year. According to reports, SK Hynix president Li Shixi said recently that the company plans to start the production of the fourth generation (1a nm) DRAM products with EUV lithography machine at M16 in Lichuan plant area in the second half of next year. The M16 plant will be completed by the end of this year, and manufacturing equipment will be introduced in the first half of next year. At present, the laboratory is in the process of preparation and is expected to start mass production next year. < p > < p > for memory, it is faced with the problem of miniaturization just like CPU logic process. EUV lithography can reduce multiple exposure process, provide process precision, and reduce production time, cost and improve performance. < / P > < p > of course, the price of EUV process is not without. The unit price of EUV lithography machine is more than 1 billion yuan, and the output is not as good as that of traditional DUV lithography machine, which means that the initial cost will be higher. Before SK Hynix, Samsung also announced the use of EUV technology to produce memory. The 16GB lpddr5 memory released not long ago has been used, with a bandwidth speed of 6400mbps (equivalent to 6400mhz), which is 16% faster than the current 12gb lpddr5-5500. In the three major memory manufacturers, only Meguiar is not very enthusiastic about EUV technology. However, with the first two manufacturers adopting EUV technology, Meguiar’s subsequent ideas may also change. Privacy Policy
