Abstract:

The basic device and encapsulation designs for the 500-volt500-ampere switch are given, and the device fabrication process outlined. The problems with silicon material for such a large area device are treated in detail since their solution or circumvention constituted a major portion of the program. Equivalent emphasis is given to device characterization since the 500-ampere current level - with all of its implications - is far in excess of commercially available silicon controlled rectifiers. Data are reported on fifty final device samples delivered to the Navy Department. These devices are the largest silicon controlled rectifiers ever fabricated and represent a tremendous advance in the state-of-art of semiconductor power switches. Author
