Abstract

An oxygen or nitrogen ion beam is implanted into a polycrystalline silicon or in an amorphous silicon layer, or a single crystal device body or layer, on a semiconductor substrate to an extent sufficient to convert the polycrystalline silicon layer, the amorphous layer or the single crystal device body or layer into a semi-insulating layer having a resistivity of 10.sup.7 to 10.sup.11 ohm-cm, which has improved passivation property.
