"We are preparing to meet the water demand in the future. This is a stress test," TSMC said The chip giant said it had not yet seen the impact of water supply restrictions on production. < / P > < p > two chip companies, vanguard and United Microelectronics, have also signed a water supply contract for waterwheel, saying it will not affect production.

Many factories have been required to shut down due to Blizzard attacks in Austin, US financial media reported on the website of Barron weekly on the 17th, in order to ensure the power supply for residents. Local factories of chip giants such as NXP semiconductor, Samsung Electronics and Infineon have been shut down. < / P > < p > according to Citibank, the factory in Austin accounts for about 28% of Samsung's total capacity. NXP semiconductor is the world's leading supplier of automotive chips, accounting for nearly half of the company's total sales last year. Infineon is also an important supplier of automotive chips. Its factory in Austin mainly produces memory chips for the automotive and industrial markets, and its revenue last year accounted for about 5% of the company's total revenue. Affected by this, as of the US stock market closed on the 17th, the shares of NXP semiconductor and Infineon fell by 2.9% and 3.1% respectively, while the shares of Samsung Electronics on the South Korean stock market also fell by 2%. < / P > < p > for some time, due to the shortage of global automotive chip supply, some automotive manufacturers have to idle their production lines. British "Financial Times" analysis said that the blizzard weather in the United States led to the shutdown of a number of chip factories, which may aggravate the global chip supply shortage. On the 17th, IHS Markit, a data analysis company, said that the shortage of chips will reduce global production by nearly 1 million vehicles in the first quarter of this year. It was significantly higher than previously expected. Volvo Group announced on the 18th that it will cut car production in Belgian factories due to chip shortage.

Japan's Renesas electronics, which ranks third in the global car chip market share, has a major factory in Ibaraki Prefecture, which is adjacent to Fukushima Prefecture. Affected by the earthquake, there was a blackout. At present, the power supply has been restored, and the buildings in the factory have not been damaged, but in order to confirm whether the production equipment and chip products in the dust-free workshop are intact, Renesas electronics suspended the production line of the factory. < p > < p > < b > [Liu Deyin: TSMC's 3nm and major process nodes in the future will be launched as scheduled] < / b > < / P > < p > source: mobile phone China < / P > < p > [CNMO news] recently, Liu Deyin, chairman of TSMC, was invited to make a special speech on the opening line of the International Solid State Circuit Conference 2021 (ISSCC 2021), pointing out that TSMC's 3nm process is advancing as planned, even ahead of expectations. 3nm and the main process nodes in the future will be launched and put into production as scheduled. TSMC's 3nm process is expected to be put into trial production in the second half of this year and mass production in the second half of next year. < / P > < p > Liu Deyin pointed out that the pace of semiconductor process miniaturization has not slowed down, Moore's law is still valid, and TSMC's 3nm is ahead of the expected progress. As for the electric crystal architecture after 2nm, it will turn to the nano sheet architecture around the gate (GAA), and the extreme ultraviolet (EUV) technology can support 1nm. < p > < p > TSMC will launch 5nm process and enter mass production in 2020. Compared with 7Nm, the logic density increases by 1.83 times, the operation speed increases by 13%, and the operation power consumption decreases by 21%. TSMC expects to launch the 3nm process in 2022, which will increase the logic density by 1.7 times compared with 5nm, increase the computing speed by 11%, and reduce the computing power consumption by 27%. < / P > < p > < / P > < p > TSMC recently announced that it will set up an R & D center in Japan to expand 3D IC material research. Liu Deyin also mentioned TSMC's technological innovation in new materials, including hexagonal boron nitride (hBN), which is close to mass production. He stressed that system integration is the future development direction of semiconductors, and the chip is the key to make the technology develop in the right direction, while TSMC's advanced SOIC packaging technology can realize 3D chip stacking.
