Abstract

Abstract A diode in which a first semiconductor region of one conductivity type and a second semiconductor region of a conductivity type opposite to that of the first semiconductor region are joined through an intrinsic semiconductor region or a low concentration impurity semiconductor region. The diode has a control electrode provided over the intrinsic semiconductor region or the low concentration impurity semiconductor region through an insulative film.
