Abstract

PURPOSE:To avoid decrease in thershold voltage, when providing a reverse conductivity type island-shape region in a one conductivity type semiconductor substrate and forming an MOS type element in this region, by providing a high-impurity-concentration region of the same conductivity type as the island-shape region under a source or a drain. CONSTITUTION:A reverse conductivity type island-shape region 22 is provided on a top layer section of one conductivity type semiconductor substrate 21, a one conductivity type source region 23 and a drain region 24 are dispersingly formed in this region 22, and a gate electrode 25 is attached through a gate insulation membrane 26 onto the region 22 exposed between these regions, so that an MOS type semiconductor substrate device is formed. In this consitution, regions 30 and 30', which has the same conductivity type as the region 22 but a higher impurity concentration, are provided in advance at least on the region 23 and 24 or under these regions. It is possible, by doing so, to prevent stretching and piercing of a depletion layer 27 formed in the regions 23 and 24 and also to increase mutual conductance.
