TSMC will unveil its 3nm production node in April

TSMC will unveil its 3nm production node in AprilChinese MyDrivers reports that at a talk last week, TSMC announced that its capital expenditure in 2020 will be $15-16 billion, of 80% which will be invested in advanced capacity expansion, including 7nm, 5nm and 3nm production nodes. At this talk, TSMC did not announce the 3nm process, because they will host a special press conference in April and will disclose the details of the 3nm process.

Its only other direct competitor is Samsung, which announced the 3nm process first last year. Samsung will definitely give up FinFET transistors and will turn to GAA surround-gate transistor technology instead. Samsung's 3nm process is divided into 3GAE and 3GAP, the latter has better performance, but the first generation is the first generation of GAA transistor process 3GAE. According to the official statement, based on the new GAA transistor structure, Samsung has manufactured MBCFETs (Multi-Bridge-Channel FETs) by using nanochip devices. This technology can significantly enhance transistor performance and will replace thr FinFET transistors technology. In addition, MBCFET technology can also be compatible with existing FinFET manufacturing process technologies and equipment, thereby accelerating process development and production.

At the Japan SFF conference in 2019, Samsung also announced the specifications of the 3nm process. Compared with the current 7nm process, the 3nm process can reduce the core area by 45%, reduce power consumption by 50%, and improve performance by 35%. Samsung plans to invest US$116 billion in its semiconductors business by 2030. Since it is behind TSMC at 7nm and 5nm nodes, Samsung bets on the 3nm node and hopes to surpass TSMC to become the largest wafer foundry at this node. Therefore, Samsung has high hopes for the 3GAE process, and mass production will be as soon as 2021.

As for TSMC, they also invested heavily in the 3nm node. Last year, they announced that they invested $19.5 billion in the construction of a 3nm factory and will officially start construction in 2020. However, technical details have not been disclosed, especially whether TSMC will choose GAA transistors like Samsung or will continue improving the FinFET technology. Източник
