Slide 1 - Semiconductors

Devices and Fabrication Process

Building Blocks of Modern Electronics

Slide 2 of 6

Slide 2 - What Are Semiconductors?

Conductivity between conductors and insulators
Key materials: silicon (most common), germanium, gallium arsenide
Doping: impurities create n-type (excess electrons) or p-type (excess holes)
p-n junctions enable device functionality

Slide 4 - Fabrication Workflow

Step	Description
Thermal Oxidation	Grow thin oxide layer on wafer
Thin-film Deposition	Add material layers (insulating, conducting)
Ion Implantation	Dope with impurities for n/p-type
Photolithography	Pattern using light-sensitive resist and masks
Etching	Remove unwanted material
