February 9 - The second phase of the Taichung campus expansion development plan of the Central Taiwan Science Park, where TSMC's 2nm fab is at stake, passed the environmental assessment assembly yesterday (8), with an estimated output value of NT$501.4 billion and will provide 4,500 jobs. This means that TSMC's 2nm plant will be launched soon.
It is reported that the Environmental Protection Agency (EPA) held an EIA meeting yesterday, and one of the cases was the CSC II expansion project. It is reported that TSMC's 2nm plant will be located there, and the case has received high attention. After three reviews by the task force, it passed the preliminary environmental assessment at the end of last year, and then successfully passed the final hurdle of the environmental assessment at the EIA conference yesterday.
According to the information from the National Science Council's Central Taiwan Science Administration, the development area of the second phase of the Central Taiwan Science Extension was reduced from 94.62 hectares to 89.75 hectares, but the green area was maintained at 12.99 hectares.
In terms of water consumption, the original plan was 100,000 CMD (tonnes per day), which was slightly reduced to 95,565 CMD in line with the reduction in area, and the commitment to 100% reclaimed water in the end, except for water for people's livelihood, with a water recycling rate of 84% for the whole area, and to set up its own reclaimed water treatment facilities, which can produce 20,000 CMD of reclaimed water in the end. In terms of electricity consumption, the original plan of the total electricity consumption of 975MW was also reduced to 925MW, and the commitment to move in semiconductor manufacturers to obtain 25% renewable energy each year, and use 100% renewable energy in 2050.
In this regard, TSMC said yesterday that it was "happy to see it happen" and stressed that it would uphold its consistent commitment to green manufacturing through climate and energy, water management, resource recycling and air pollution prevention and other aspects to practice concrete actions.
It is understood that TSMC's 2nm plants are planned to be set up in Zhuche Baoshan and Zhongke respectively. TSMC Chairman Deyin Liu pointed out at the end of last year at the 3nm mass production ceremony that the 2nm fabs currently under preparation are located in Hsinchu and Central Science Park respectively, with a total of six phases of construction all continuing to progress according to plan.
TSMC's president, Wei Zhejia, also mentioned at the January conference this year that TSMC's 2nm progress was better than originally expected, maintaining the risk of trial production in 2024 and mass production in 2025, which is progressing well.
According to the data, TSMC entered the development stage of 2nm N2 process technology last year, focusing on test carrier design and actual work, photomask production and silicon trial production, etc. The main progress is to improve the basic process settings, transistor and wire performance. In lithography, TSMC's R&D organisation is supporting the development of 2nm technology by improving wafer yields to achieve reliable images to support 3nm pilot production, and enhancing the application of extreme ultraviolet (EUV) light, reducing material defects and improving flattening capabilities.
At the previous TSMC Technology Forum 2022, TSMC also debuted some of the technical specifications for its next-generation advanced process N2 (i.e. 2nm process): compared to its N3E (a lower-cost version of 3nm) process, TSMC's 2nm process will deliver 10-15% higher performance at the same power consumption; while TSMC's 2nm process will consume 23-30% less power at the same performance. Transistor density is only increased by 10%.
