Abstract
A permeable base transistor includes a source region and a drain region confronting each other in a semi-insulating semiconductor layer, a gate electrode having a current penetrating aperture through which a channel current flows disposed between the source region and the drain region and the source and drain regions, and the gate electrode are disposed so that the channel current flows transverse to the thickness of the semi-insulating semiconductor layer.
