ABSTRACT:
A semiconductor device for use in a bootstrap circuit comprising: first and second MIS field effect transistors connected in series between a power supply line and ground; third and fourth MIS field effect transistors connected in series between the power supply line and ground; a capacitor connected between the gate and source of the third MIS field effect transistor, and; a fifth MIS field effect transistor connected between first and second nodes, the first node connecting the first and second MIS field effect transistors, and the gate of the third MIS transistor, the second node connecting the third and fourth MIS field effect transistors being connected to an output of the device, wherein a p-n junction portion which is connected to the capacitor is protected by a cover for preventing light from penetrating thereinto.
