  • Patent number: 9892920
    Abstract: A method includes providing a first part, a second part and a bonding material between the first part and the second part. The first part and the second part are made of a first material selected from a group consisting of silicon and germanium. The bonding material includes a second material that is different than the first material. The method includes arranging the first part, the bonding material, and the second part in a furnace; and creating a bonded part by heating the first part, the second part and the bonding material to a predetermined temperature for a predetermined period followed by a predetermined solidification period. The predetermined temperature is greater than 1.5 times a eutectic temperature of an alloy including the first material and the second material and less than a melting temperature of the first material.

  • Patent number: 9842976
    Abstract: Various embodiments of light emitting devices, assemblies, and methods of manufacturing are described herein. In one embodiment, a method for manufacturing a lighting emitting device includes forming a light emitting structure, and depositing a barrier material, a mirror material, and a bonding material on the light emitting structure in series. The bonding material contains nickel (Ni). The method also includes placing the light emitting structure onto a silicon substrate with the bonding material in contact with the silicon substrate and annealing the light emitting structure and the silicon substrate. As a result, a nickel silicide (NiSi) material is formed at an interface between the silicon substrate and the bonding material to mechanically couple the light emitting structure to the silicon substrate.
