Sample interview questions: Have you ever worked with plasma-based material processing techniques? If so, can you provide examples?
Sample answer:
Examples of Plasma-Based Material Processing Techniques:
-
Plasma Enhanced Chemical Vapor Deposition (PECVD): Uses plasma to catalyze the deposition of thin films from volatile precursors. Applications include creating high-quality insulators, semiconductors, and solar cell materials.
-
Plasma Ion Implantation (PII): Implants ions into materials using plasma to modify their surface properties. Used for semiconductor device fabrication, wear resistance enhancement, and medical implant sterilization.
-
Plasma Nitriding: Enriches the surface layers of metals with nitrogen using plasma. Improves wear resistance, corrosion resistance, and biocompatibility.
