This is pretty good...simplifies the process and some of the items are out of order, but it describes the process pretty well.

Keep in mind, even 20 year old chips have 6-700 steps in their process...it's a giant loop of Etch, Photo, Implantation, Furnace, Chemical Vapor Deposition, Physical Vapor Deposition, Chemical Mechanical Planarization, etc...don't forget the measurement steps and defect scans. State of the art chips take 3-4 months to complete this process and it's well over a thousand steps.

Months?! Wow, I had no idea. So it's a very long pipeline.
