Various embodiments of the present disclosure disclose improved silicon carbide (SiC) power devices and methods of fabrication of such devices. A SiC power device includes a semiconductor base material with a first side and a second side and a first metallic layer disposed on the first side of the semiconductor base material that forms ohmic contacts and Schottky contacts. The SiC power device may be fabricated by forming a first metallic layer on a first side of a semiconductor base material to form a Schottky contact, forming a second metallic layer over the first metallic layer to form a reflective barrier covering the Schottky contact, removing one or more portions of the second metallic layer to expose a first portion of the first metallic layer, and forming silicide portions on the first metallic layer to form ohmic contacts within the Schottky contact.
