Explanation: Epitaxial growth is arranging of atoms in single crystal fashion upon a single crystal substrate, so that the resulting layer is an extension of the substrate crystal structure. 5. Why oxidation process is required?
A. To protect against contamination
B. To use it for fabrication various components
C. To prevent diffusion of impurities
D. All of the mentioned

A. To protect against contamination B. To use it for fabrication various components C. To prevent diffusion of impurities D. All of the mentioned
Explanation: Oxidation provides extreme hard protective coating, thus protecting against contamination and by selective etching, it can be made to fabricate components. 6. Mention the chemical reaction for oxidation process
