Bipolar Transistors Having Fixed Gain Characteristics
US Patent:
4160986, Jul 10, 1979
Filed:
Aug 2, 1976
Appl. No.:
5/710727
Inventors:
David M. Johnson - Lubbock TX
International Classification:
H01L 2972
US Classification:
357 36
Abstract:
Disclosed is a bipolar transistor comprising a semiconductor body having first and second opposed surfaces with opposing edge surfaces and emitter, base and collector regions in the body with an emitter-base junction between the emitter and base regions and a base-collector junction between the base and collector regions. The emitter-base junction extends across the semiconductor body and terminates at the edge surfaces such that injection across the emitter-base junction is substantially uniform across the semiconductor body. In one arrangement, two collector regions are provided, one of which is coupled to the base contact in order to control the gain of the transistor.
