A FIELD EFFECT TRANSISTOR OF SIC AND A METHOD FOR PRODUCTION THEREOF

摘要

A transistor of SiC comprises superimposed a drain (13), a highly doped substrate layer (1), a low doped n-type drift layer (2), a p-type base layer being divided into a first lower highly doped base sub-layer (3) and an upper low doped second base sub-layer (4) on top thereof, a highly doped n-type source region layer (6) and a source (11). It also has an insulating layer (8) with a gate electrode (9) thereon arranged on top of the base layer and extending laterally from the source region layer to a n-type layer (7) connected to the drift layer.
