Abstract
The present invention provides a semiconductor laser diode prevents not only the adhesion of the upper electrode but the heat dissipation of the mesa from degrading. The laser diode includes a substrate, portion of which forms a mesa including an active layer, an insulating layer formed so as to bury the mesa, and an electrode formed on the mesa and the insulating layer. This insulating layer may be selected from SiO, SiON, SiN, AlOor ZrOand formed by the inductive coupling plasma-enhanced chemical vapor deposition (ICP-CVD) technique.
