Abstract:
1. A flip chip type of light-emitting semiconductor device comprising: a substrate; group III nitride compound semiconductor layers formed on said substrate, said layers comprising a p-type semiconductor layer; a positive electrode including at least one layer of a first positive electrode layer which is formed on or above said p-type semiconductor layer and reflects light toward said substrate, said first positive electrode layer comprising at least one of rhodium (Rh), ruthenium (Ru), and an alloy including at least one of these metals; and a first thin-film metal layer, comprising at least one of cobalt (Co), nickel (Ni), and an alloy including at least one of these metals, formed between said p-type semiconductor layer and said first positive electrode layer, wherein said substrate transmits said light reflected from said positive electrode, and light is emitted from a substrate side of said light-emitting device.
