Abstract:
In a semiconductor device, an epitaxial substrate includes a SiC (silicon carbide) substrate and a GaN (gallium nitride) epitaxial layer formed on the SiC substrate. A multi-layer wiring structure is formed on the front-face side of the epitaxial substrate, and includes at least one metal wiring layer and an organic interlayer dielectric. A back-face metal layer is formed on the back face of the epitaxial substrate. At least one via hole is formed in the epitaxial substrate, and is configured to provide a connection between the multi-layer wiring structure and the back-face metal layer.

Claim (Index 2):
The semiconductor device according to  claim 1 , wherein via hole etching for forming the via hole is performed under a condition that does not involve degradation of the interlayer dielectric.
