Abstract:
In one aspect, a method of manufacturing a trench type Schottky diode may include steps of providing a substrate, depositing an epitaxial layer on top of the substrate, forming one or more trenches on top of the epitaxial layer, forming a first implantation region in a bottom portion of each trench, forming a second implantation region in a sidewall portion of the trench, depositing an ohmic contact metal on an opposite side of the substrate, and depositing a Schottky contact metal on top of the epitaxial layer and filling the Schottky contact metal in each trench. In one embodiment, the substrate is made by an N +  type SiC, and the epitaxial layer is made by an N-type SiC on top of the substrate. In another embodiment, the first implantation region can be doped with P-type impurity and the second implantation region can be doped with N-type impurity.
