Document Type and Number:
Japanese Patent JP5285835
Kind Code:
B2
Abstract:
Disclosed herein is a high-reliability semiconductor device. The laser diode includes: a substrate; a multi-layer film including a first conductivity type cladding layer provided on the substrate, a first conductivity type guide layer provided on the first conductivity type cladding layer, an active layer provided on the first conductivity type guide layer, a second conductivity type guide layer provided on the active layer, and a second conductivity type cladding layer provided on the second conductivity type guide layer, each of the layers being made of a nitride-based III-V group compound semiconductor; a first protective layer made of nitride and provided on a light emitting surface of the laser diode; and a second protective layer provided on the first protective layer and made of nitride having a refractive index different from that of the first protective layer.
