Abstract: A semiconductor device includes a semiconductor substrate, a first anode electrode, and a second anode electrode. The first anode electrode is disposed on the semiconductor substrate. The second anode electrode is spaced from the first anode electrode on the semiconductor substrate around the first anode electrode. At least any of a first end of the first anode electrode on a second anode electrode side and a second end of the second anode electrode on a first anode electrode side is covered with a SInSiN film.
