You could guide me (and many others) to some references how it works. Perhaps with some images to go. I fully appreciate that things are not always as they seem but asking why would I understand is not very fruitful.For you yes. Why would you understand IC manufacturing?
You're saying that we can't be sure by looking or by measuring. So there is no way to know what is real/licenced and what is not? Perhaps, I have no problem with the general idea. But why would I take your word for it?
