发明名称 自己整合ソースおよびウェル領域を有する炭化珪素パワーデバイスならびにその製造方法
摘要 <p>Silicon carbide semiconductor devices and methods of fabricating silicon carbide semiconductor devices are provided by successively etching a mask layer to provide windows for formation of a source region of a first conductivity type, a buried silicon carbide region of a second conductivity type opposite to the first conductivity type and a second conductivity type well region in a first conductivity type silicon carbide layer. The source region and the buried silicon carbide region are formed utilizing a first window of the mask layer. Then, the well region is formed utilizing a second window of the mask layer, the second window being provided by a subsequent etch of the mask layer having the first window.</p>
