Title: Epitaxial field-effect transistor - has electrodes applied to flanks of etched-away epilayer
Inventor: BENEKING HEINZ PROF DR RER NAT
IPC: H01L29/808
Filed: 1973-04-30
Abstract: A field-effect transistor consists of a thin (0.3-0.5 mu) epilayer of the n-type on a semiconductor substrate (GaAs). The epilayer is etched away at one side and the source electrode is applied to the flank created thereby. The gate is formed in the close vicinity of the source, and the drain electrode is arranged on the side of the gate away from the source, also on the epitaxial layer. This results in a considerable reduction of the input series resistance of the field-effect transistor. This in turn means a sharp increase in the critical threshold frequency.
