finfet IC Yield会很高吗 ?

6nm chip  finfet IC Yield会很高吗 ?

只做过0.18um~ 0.11um 这类cp yield 99~ 97% 是基本要求 .  但听说三星10nm 下 60% 就算可  .    因advance process 会leaking  ..function 等各方面问题,   

那一般22nm ,  28nm  , 65nm  SOCchip  yield 到底多高 ?  新闻说 tsmc 3nm 60% 就能达标

首先看你设计，是你设计出来的，其次看你们的测试分bin; 同样的GPU算力设计流片，实际能跑4G主频，还是3G主频,甚至2G, 你自己可以分bin的，都用上，良率应该还可以的，至少T是这样子。
当然，你如果只统计能跑4G主频的，那确实良率有限。

yield都是跟spec走的

Media reports said TSMC has already boosted the yield of its 7nm and 5nm chips to 93.5% and 80%



start of 2023, TSMC's 4nm yield rate was around 70–80%, while Samsung's was still around 50%.



Samsung's current yield rate on 7nm is about 80%
