Semiconductor device with reduced number of trough holes and method of manufacturing the same

摘要

A semiconductor device with reduced number of through holes is disclosed. A source region and a highly doped contact layer are connected by a conductive layer made of silicide formed on the surface of the source region and the highly doped contact layer commonly, and a drain region and a output electrode are connected by a another conductive layer made of silicide. The conductive layer interconnecting the source region and the highly doped contact layer, and the conductive layer interconnecting the drain region and the output electrode are formed in one step as they are disposed beneath an insulation layer on the surface of the semiconductor substrate
