Slide 4 - Doping: n-type vs p-type

n-type Semiconductor Doped with Group V impurities (phosphorus, arsenic, antimony) Provides extra electrons (donors) Majority charge carriers: electrons (negative)

p-type Semiconductor Doped with Group III impurities (boron, gallium, indium) Creates holes (acceptors) Majority charge carriers: holes (positive)

Slide 5 - Semiconductor Device Fabrication

Process Step	Description
Photolithography	Pattern transfer using light-sensitive materials
Thermal Oxidation	Grow thin oxide layers on wafer
Thin-film Deposition	Add layers of insulating or conducting materials
Ion Implantation/Doping	Introduce impurities to create n/p regions
Etching	Remove unwanted material to form circuits
Wafer Dicing	Separate dies from wafer
