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 8):
The manufacturing method according to  claim 7 , further comprising removing, by means of ultrasonic cleaning, impurities that have adhered to the epitaxial substrate.
