  • Method of fabricating a semiconductor device with high heat conductivity
    Patent number: 5538919
    Abstract: A VCSEL having a first mirror stack positioned on the surface of a substrate, an active region positioned on the first mirror stack and substantially coextensive therewith, and a second mirror stack positioned on the active region, the second mirror stack forming a ridge or mesa having a side surface. A metal contact layer is positioned on the side surface of the ridge or mesa and on portions of an end of the ridge or mesa to define a light emitting area, and a layer of diamond-like material is electrolytically plated on the metal contact layer so as to form a heat conductor to remove heat from the laser.
