3
Project aims: Acquaintance with detector fabrication
Performance measurement
4
Kinds of detectors Coaxial Planar
5
Detector fabrication Crystal preparation:
Cutting a crystal of a required shape. Making a p–n junction. Cutting out a protecting ring. Temperature evaporation Au at the p–n junction side.
6
Detector fabrication Crystal preparation:
Etching and oxidizing for an ohmic contact. Temperature evaporation of Pd and Au upon a prepared surface. Final etching and protecting the surface from the environment.
