This eBook is for people with technical interest for the basics of the structure of microchips. 

What is a semiconductor? Why it is so interesting for the electronic? How to use the semiconductor and how is it produced? 

Overview of the basic process steps needed to build a microchip like photolithography, oxidation, deposition, etching, doping ...

A short discussion of a CMOS circuit as an example used at the process followed at the next chapter.  

Diode --> Transistor --> Inverter

Starting with the silicon wafer a inverter is realized.  

A really short look at the packaging to bridge the wafer to the final microchip.
