Sample interview questions: Have you ever worked with plasma-based laser-induced incandescence techniques? If so, can you provide examples?
Sample answer:
-
Laser-induced breakdown spectroscopy (LIBS):
Utilizing a high-power laser to form plasma from a sample’s surface, LIBS analyzes its elemental composition. I have extensive hands-on experience with LIBS setups, ranging from optimizing laser parameters to collecting and interpreting spectral data. Employing LIBS, I have successfully analyzed diverse materials like metals, ceramics, polymers, and biological tissues. -
Plasma-based light sources for extreme ultraviolet (EUV) lithography:
EUV lithography is a cutting-edge technique for manufacturing semiconductors with smaller feature sizes. I have worked on developing plasma-based light sources that generate EUV radiation by irradiating targets with a high-power laser. My contributions have focused on optimizing plasma conditions, designing novel target geometries, and characterizing the output EUV spectrum. -
Plasma-enhanced chemical vapor deposition (PECVD):
PECVD utilizes plasma to deposit thin films from gaseous precursors. I … Read full answer
