DEFINITION

Classification: 438/FOR.154

Ion beam implantation:

Foreign art collection for processes involving penetration of the surface of a semiconductor substrate with ion beams, i.e., charged negative or positive particles, functioning as a dopant carrier or dopant modifier possessing sufficient kinetic energy to form a junction region in the substrate, e.g., P+, P-, N+, N-, PN, NPN, etc., metal semiconductor junction exhibiting rectifying properties, etc.
