ABSTRACT:
A method of switching-off a monolithically integrated light-activated thyristor structure in an n-p-n-p-n-p sequence is herein presented. In the method a monolithically integrated semiconductor thyristor structure is illuminated through an optical aperture to convey light into the embedded switching semiconductor structure to electrically short a thyristor cathode and a thyristor base through a floating gate to turn off the thyristor.
