Abstract:
1. An overvoltage-proof light-emitting semiconductor device comprising: (a) a substrate of substantially electrically conducting material having a first and a second opposite major surface; (b) a main semiconductor region formed on the first major surface of the substrate and comprising a plurality of semiconductor layers for generating light, the main semiconductor region having a first major surface from which the light is emitted, a second major surface held against the first major surface of the substrate, and a hole extending therethrough between the first and second major surfaces thereof; (c) a first electrode covering a part of the first major surface of the main semiconductor region and the hole of the main semiconductor region, the first electrode being electrically connected to the first major surface of the main semiconductor region and having a function of a bonding pad; (d) a second electrode formed on the substrate; and (e) an overvoltage protector disposed between the first electrode and the second major surface of the substrate and electrically connected to both of the first and the second electrode.
