Lecture 02/22 Flashcards
1
Q
What are the 2 heat treatments for semiconducting materials? Explain what they do
A
- Predeposition step using gas
- Drive in diffusion where oxide layer is formed
Put a layer of the impurities on the surface, the impurities then get pushed into the further layers of the material
2
Q
What is interdiffusion?
A
Migration of impurity atoms
3
Q
What is self diffusion?
A
Host atom migration
4
Q
What are the two types of diffusion?
A
Vacancy and interstitial
