Class 03: Semiconductor Processing
Class 03: Semiconductor Processing Implantation is functionally similar to diffusion, but here the atoms are "shot" into the wafer at high velocity (across a very strong electric field) and they embed themselves into the wafer surface.
What is a Silicon Wafer? Silicon Valley Microelectronics
Semiconductor device fabrication is the process used to create the integrated circuits that are present in everyday electrical and electronic devices. It is a multiple-step sequence of photolithographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material.
