  • Patent number: 5559817
    Abstract: A compliant layer metallization for relieving thermal and mechanical stress developed between a semiconductor and a semiconductor submount. The compliant layer metallization includes a compliant layer, a wetting layer and a barrier layer. The compliant layer provides thermal and mechanical stress relief. The wetting layer ensures adequate wetting during soldering. The barrier layer prevents diffusion of bonding material into the compliant layer and/or into the semiconductor during solder-bonding. The compliant layer metallization design promotes ease of manufacturing.
