Filed: 1989-06-29
Abstract: PURPOSE:In a transistor being formed within the silicon film on an insulating film, to absorb positive holes generated by collision ionization phenomena so as to improve breakdown strength by providing a region having a concentration higher than the substrate concentration. CONSTITUTION:When a source electrode 42 is grounded and positive voltage is applied to a gate electrode 5, a transistor becomes ON conditions. When positive voltage is applied to a drain electrode 41 in this condition, electrons flow from a source diffusion layer 32 to a drain diffusion layer 31. Moreover, when the electrons get energy enough being accelerated by an electric field, they collide against a silicon lattice and generate electron-hole pairs, and the electrons generated here are absorbed in a layer 31 along a drain electric field. the positive holes flow in a substrate and are absorbed in a P<+> diffusion layer 33 in high positive hole density. Hereby, they do not accumulate in the vicinity of the layer 32, and also potential barriers between the source and the substrate cease to be low. As a result, kink phenomena become small or cease to appear.
