    • A host substrate and method of making a host substrate for nitride based thin-film semiconductor devices are provided. The method includes the steps of providing a silicon layer (100), etching a pattern of holes (102) in the silicon layer (100), plating the silicon layer (100) with copper (300) to fill the holes (102) formed in the silicon layer (100), bonding the silicon layer (100) to a gallium nitride (GaN) layer (500), the GaN layer (500) attached to a sapphire substrate (502). The host substrate is configured to address the coefficient of thermal expansion (CTE) mismatch problem and reduce the amount of stress resulting from such CTE mismatch. A combination of metal and semiconductor materials provide for the desired thermal and electrical conductivity while providing for subsequent dicing and incorporation of the finished semiconductor into other circuits.
    • 提供了一种主衬底和制造用于氮化物基薄膜半导体器件的主衬底的方法。 该方法包括以下步骤:提供硅层(100),蚀刻硅层(100)中的孔(102)图案,用铜(300)电镀硅层(100)以填充所形成的孔(102) 在硅层(100)中,将硅层(100)与氮化镓(GaN)层(500)接合,附着到蓝宝石衬底(502)的GaN层(500)。 主机基板被配置为解决热膨胀系数(CTE)失配问题,并减少由这种CTE失配引起的应力的量。 金属和半导体材料的组合提供期望的热导电性和导电性,同时提供随后的切割和将成品半导体结合到其它电路中。
