Claim 0:
1. A semiconductor device, comprising:
a substrate including a semiconductor layer and a plurality of electrodes over the semiconductor layer;
an insulating layer containing silicon provided over the substrate and covering the semiconductor layer and the plurality of electrodes of the substrate, the insulating layer containing silicon being at least one of silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, or silicon oxycarbide;
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 and provided between the insulating layer containing silicon and the semiconductor layer;
a collection of first metal particles provided on a surface of the insulating layer containing silicon; and
a first insulating diamond layer provided 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.
