Filed: 1979-03-20
Abstract: PURPOSE:To provide a novel MISFET having flat VD-ID characteristics by connecting a larger energy forbidden band region than a semicodncutor crystal region to a drain region. CONSTITUTION:A p-type semiconductor layer 42, a semiconductor layer 43 having lower energy forbidden band width than the layer 32 and an n-type semicodncutor layer are sequentially epitaxially grown on an n-type semiconductor substrate 41. A V shaped groove 45 is formed thereon, an insulating layer 46 of Al2O3 or the like is formed on one inside surface, and a gate electrode 47 is formed thereon. Thus, a MISFET is formed with the layer 44, as a source region, the substrate 41 as a drain region, and layers 42, 43 as channel regions. Since the layer 42 has higher energy forbidded band width than the layer 43, when the drain voltage VD is raised, the drain current ID becomes falt. When the equal semiconductor region 52 to the layer 42 is formed between the region 44 and the region 43, the MISFET may be formed in transfer gate type.
