Abstract
PURPOSE: To enhance the pressure resistance of a planer type element by treating the element with an aqueous solution of a hydrogen peroxide system to make negative the charges on the interface of an insulating film and a silicon substrate, thus enabling the easy widening of a depletion layer in the vicinity of the surface of the substrate of a N type base zone.
