Abstract

PURPOSE:To provide high withstand voltage without loss of switching characteristic and to enable the interruption of large current in a field effect transistor having a buried gate layer by forming the density and thickness of the gate layer in two-stage structure. CONSTITUTION:A p<+> type anode layer 2 is formed on one surface of an n<-> type semiconductor substrate 1, and the first buried gate layer 31 of high impurity density and the second buried gate layer 32 for forming a channel 5 are formed on the other surface. After an n type epitaxial layer 4 is formed on the surface of forming the buried layer, an n<+> type cathode layer 6 is formed. Then, the part of the layer 4 is etched and removed, and a gate electrode leading recess is formed. Thereafter, a silicon oxidized film 7 is formed for protecting the surface, a gate electrode 81, a cathode electrode 82 and an anode electrode 83 are formed, and a field effect thyristor is completed. In figure, reference numeral 9 illustrates a cathode electrode pressing cathode electrode plate.
