introduction to Semiconductor engineering 1

3/2

Why study semiconductor = essential in electronics, its everywhere. 
Controlling electron movement is very important. Without transistor, we cannot do anything today.

How electrons move in a solid material?
Why is there an energy band in a solid material?
how to produce electronic devices?

variations method = DERT (Doping, Energy, Radiation, Temperature)

movement of excess carriers in solid?
process the silicon wafer -> cut them into pieces

basic unit of one transistor = SDG (source drain gate) 사단장
one unit of transistor is like 10nm these days

how to control electron flows에 대해 대답할 수 있어야!
 1. electron flows는 (물의 흐름), 전류 제공은 전압 (수압).
 2. 전압으로 흘린 전류를 gate (수도꼭지)로 컨트롤.

surface potential과 periodic potential 이해에도 도움.
