Abstract:
In one aspect, a method for manufacturing a 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, producing an implantation region at a bottom portion of each trench, providing an ohmic contact metal on an opposite site of the substrate, and depositing a Schottky contact metal on top of the epitaxial layer and filled into each trench to form a Schottky junction between the Schottky contact metal and the epitaxial layer, and between each trench and the epitaxial layer. In one embodiment, the substrate is made by N +  type Silicon Carbide (SiC) and the epitaxial layer is made by N −  type SiC. In another embodiment, the step of producing an implantation region includes a step of doping P-type impurity into the bottom of each trench.
