JFET Device With Virtual Source and Drain Link Regions and Method of Fabrication

摘要

A junction field effect transistor comprises a semiconductor substrate. A source region of a first conductivity type is formed in the substrate. A drain region of the first conductivity type is formed in the substrate. A channel region of the first conductivity type is formed in the substrate. A gate region of a second conductivity type is formed in the substrate between the source and drain regions. A first virtual link region is formed in the substrate between the gate region and either the source region or the drain region. A dielectric material overlays the first virtual link region. A first electrode region overlays the dielectric material.
