Description:An assembly is formed by bonding the semiconductor wafer 12 to a submount 17 with a uniform wax layer The submount 17 supports and allows handling of the semiconductor wafer 12 during wafer process steps. The assembly is heated in a vacuum to remove solvent and air trapped in the uniform wax layer 14 thereby minimizing air voids which can cause a non-uniform bond. The assembly is then annealed to reduce stress on the semiconductor wafer 12 induced by differing material thermal expansion rates of the semiconductor wafer 12 , the uniform wax layer 14 , and the submount
