Semiconductor Substrates – Crystal Defects
Crystal defects play an important role in semiconductor fabrication. One type of defect is a Frenkel defect. Understanding such defects involves determining the vacancy concentration as given by Arrhenius function. I reviewed several videos to help me understand this equation:
Background Concepts
I took a detour to remind myself about activation energy, electron volts, and Boltzmann’s constant (all of which feature when studying Arrhenius function).
Line Defects
Another type of crystal defect is a line defect, e.g. edge dislocation. These videos contain additional information about edge dislocations.
Area Defects
A stacking fault is an extra plane of atoms. Some resources about stack faults:
Gettering is a process by which impurities and defects diffuse through the crystal (controlling where defects occur). This can be used to improve yield in semiconductor manufacturing as explained in this video:
