I like Asianometry. He posts detailed, but easy to understand content related especially to high tech manufacturing processes and companies, especially those in the fields of semiconductor and related industries.This is a guy in youtube with interesting videos for people with little or no knowledge about semiconductors. I liked them because I know very little about chips and their manufacturing. So for the most part it will be useless for you folks. I do know, however, that there are a couple of people here who are also not technically savvy. So here we go. From there you can find other videos from the same chap
