TSMC's 3nm yield has reached 80%

Update time : 2022-08-23 17:59:38

TSMC has confirmed that it will mass produce the 3nm process in September, but Apple's iPhone 14 series with the A16 processor can't catch up this year, or use TSMC's 5nm or improved version of the 4nm process, the first 3nm may be M2 Pro, but the output will not be too much.

The initial generation of the N3 process is mainly for early customers with superb investment capabilities and the pursuit of new processes, such as Apple and AMD, but the application is narrower and only suitable for manufacturing specific products.
TSMC's 3nm process to next year's second version of the N3E process, that is, 3nm Ehanced enhanced version, on the basis of N3 to improve performance, reduce power consumption, expand the scope of applications, compared to N5 the same performance and density of power consumption by 34%, the same power consumption and density of performance by 18%, or can be transistor density by 60%
Although the density may be such as the first generation of N3, but the N3E process will be the main force used by the major manufacturers to discuss production, including Apple's new generation of processors, such as the iPhone15’s 17 processor, the next generation of M3 processors, and AMD's future Zen5 and so on.
N3E process is expected to mass production in the second half of 2023, this year there will be trial production, a few days ago there was a leaked internal PPT shows TSMC's N3E process progress is very good, the yield rate is pleasing.
The N3E process produces 256Mb SRAM chips with yields of up to 80%, mobile and HPC chips with yields of 80%, and ring oscillators with yields of even 92%.
