Abstract:
A semiconductor power device may include a Silicon Carbide (SiC) layer having an active power device formed on a first surface thereof. An Ohmic contact layer may be formed on a second, opposing surface of the SiC layer, the Ohmic contact layer including Nickel Silicide (NiSix) with a first silicide region containing a first precipitate of non-reacted carbon disposed between the SiC layer and a second silicide region. The second silicide region may be disposed between the first silicide region and a third silicide region, and may include a mixture of a first precipitate of refractory metal carbide and a second precipitate of non-reacted carbon. The third silicide region may contain a second precipitate of refractory metal carbide. A solder metal layer may be formed on the Ohmic contact layer, with the third silicide region disposed between the second silicide region and the solder metal layer.

Claim (Index 1):
A semiconductor power device, comprising:\n a Silicon Carbide (SiC) layer having a power device formed on a first surface thereof; an Ohmic contact layer formed on a second, opposing surface of the SiC layer, the Ohmic contact layer including Nickel Silicide (NiSix) with a first silicide region containing a first precipitate of non-reacted carbon disposed between the SiC layer and a second silicide region, the second silicide region disposed between the first silicide region and a third silicide region, and including a mixture of a first precipitate of refractory metal carbide and a second precipitate of non-reacted carbon, the third silicide region containing a second precipitate of refractory metal carbide; and at least one solder metal layer formed on the Ohmic contact layer with the third silicide region disposed between the second silicide region and the at least one solder metal layer.
