For those of you who don't understand semiconductors: You do not get multi lots and multiple wafers of an "EXTREMELY SLOW CORNER." Stop letting Guy take advantage of your lack of knowledge. Given the orders which they have in the pipe and what they have communicated, I would guess there are AT LEAST 12 lots (25 wafers per lot) in the pipe. You do NOT get 12 lots processed systematically to a slow corner unless you deliberately asked for it.
You're welcome
Your argument is essentially that TSMC might have poor precision, but they wouldn't have poor accuracy. Your argument is that TSMC would not have made a systematic error in their production process. I think it is quite plausible that TSMC might have had one of their machines poorly calibrated for the low voltage threshold transistor type that is so important for bitcoin mining ASICs, but less important for most other applications.
By the way, is that username chosen to deliberately troll people?
