Claim Text:
1. A method for manufacturing a semiconductor light emitting device, the device including a semiconductor layer including a nitride semiconductor, the semiconductor layer including a light emitting section, the method comprising: forming a first metal layer on a first surface of the semiconductor layer, the first metal layer including silver or silver alloy, forming a second metal layer on the first metal layer, the second metal layer including at least one element of platinum, palladium, rhodium, iridium, ruthenium and osmium, and forming a third metal layer on the second metal layer, a thickness of the third metal layer along a direction from the first metal layer toward the second metal layer being not less than a thickness of the second metal layer along the direction; and performing sinter processing on the semiconductor layer, the first metal layer, the second metal layer and the third metal layer in an atmosphere including oxygen after the forming the first, second and third metal layers.
