If you have ever wondered how CPUs came to be from raw sand -- prepare to get learned. Intel has published a video and accompanied information document which explains their process almost step by step. The video itself will not teach you too much as it was designed to illustrate the information in the online pamphlet.
My background in education is a large part of the reason why I am excited by this video. The accompanied document is really well explained, goes into just the right amount of detail, and does so very honestly. The authors did not shy away from declaring that they do not produce their own wafers nor did they sugarcoat that each die even on the same wafer could perform differently or possibly not at all.
