Abstract

PURPOSE:To remarkable increase the static breakdown strength of MOSFET gate, by forming the gate region thinner and fitting electrodes at the both ends, and by connecting one to the gate electrode of MOSFET and by taking another as the gate input terminal, in the gate protection unit having the diodes in anti parallel connection.
