Fabricating a semiconductor device includes: forming a gate trench in an epitaxial layer overlaying a semiconductor substrate; depositing gate material in the gate trench; forming a body; forming a source; forming an active region contact trench that extends through the source and the body into the drain; forming a Schottky barrier controlling layer in the epitaxial layer in bottom region of the active region contact trench; and disposing a contact electrode within the active region contact trench.
