Classification: CPC H  Y | IPC H

Claim 8:
9. A method of manufacturing a semiconductor device, the method comprising:
preparing a substrate including a semiconductor layer and a plurality of electrodes over the semiconductor layer;
forming a passivation film containing oxide, nitride, and oxynitride containing one type or two or more types selected from aluminum, hafnium, zirconium, titanium, tantalum, and tungsten over the semiconductor layer;
forming an insulating layer containing silicon over the substrate and covering the semiconductor layer of the substrate, the plurality of electrodes of the substrate and the passivation film, the insulating layer containing silicon being at least one of silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, or silicon oxycarbide;
forming a collection of first metal particles on a surface of the insulating layer containing silicon; and
forming a first insulating diamond layer on the surface of the insulating layer containing silicon, the first insulating diamond layer being in directly contact with the insulating layer containing silicon and the collection of first metal particles.
