Field effect transistor junction system includes drain electrode with drain zones, gate electrode and channel zone, used in semiconductor technology

摘要

A field effect transistor junction (JFET) with a semiconductor body (2, 3) of first (n) conduction type has a first main surface and second main surface opposite to it, a drain electrode (D) with drain zones, a source electrode (S) with source zones, a gate electrode (G) between the source and drain zones, and a channel zone. The source electrode also has regions of a different conduction type, so that a pn-transition is obtained between the source and drain electrodes.
