The open source Handbook of Microfabrication and Microtechnology
The Wikibook on Microtechnology has been started with the intention to gather information in one place about the various applications, fabrication methods and systems to provide students, researchers and everyone else an open-source handbook and overview guide.

Part 3: FABRICATION PROCESSES
Microfabrication is largely concerned with making microchips by batch processing silicon (and an increasing number of different materials) wafers into individual chips in a cleanroom facility. Cleanrooms are used because dust must be avoided. The parts of a microchip are much smaller than the average dust particle, and a single particle can wreak havoc in a sensitive process (not only making a fault at some point on the wafer, but also contaminating process equipment)
The processes can roughly be divided into Additive and etching processes that wither add or remove material, and lithography that creates patterns on the surface.
