Classification: CPC H  G  Y | IPC G  H

Claim 14:
15. A radiation resistant circuit device, comprising:
a SiC semiconductor element equipped with a SiC integrated circuit;
a printed board on which the SiC semiconductor element is provided; and
a conductive wiring and a covering material that are arranged inside the printed board, the conductive wiring having a predetermined surface facing a bottom surface of a substrate electrode of the SiC integrated circuit, wherein
a space is formed between the bottom surface of the substrate electrode of the SiC integrated circuit and the predetermined surface of the conductive wiring, and
a parasitic capacitance is formed via the space and the covering material between the bottom surface of the substrate electrode of the SiC integrated circuit and the conductive wiring.
