LIGHT EMITTING DEVICE METHODS
First Claim
Patent Images
1. A method of making a light emitting device, the method comprising:
- providing a first multi-layer stack, comprising;
a substrate;
a submount, anda semiconductor layer between the substrate and the submount, the semiconductor layer being supported by the submount wherein the semiconductor layer and submount are selected so that a coefficient of thermal expansion of the submount differs from a coefficient of thermal expansion of the semiconductor layer by less than about 15%;
removing, at least partially, the semiconductor layer; and
removing the substrate from the first multi-layer stack to form a second multi-layer stack.
