That linked comment sounds a bit confused. Infineon, TI, and ST do not have lithography machine capacity to make all chips on their own at scale. However it is possible they do package their chips into components at their own Fabs. This Blo

Could you clarify what you think is happening? To my knowledge Infineon, TI and STMicro are all technically "fabless". The term "fabless" is also misleading because "Fabless" actually means Foundry-less. This i

Yeah, my understanding from trying to follow this as closely as possible is that there are three different supply-chain problems all happening at once, getting conflated by journalist who don't have the expertise to report on the short

If you like my first article feel free to subscribe; It's title: Rage Against the Die-ing of the Locked Silicon. It's on logic locking, something I find many engineers overlook. Going to start dropping thoughts into this substack.
