Abstract:
A transistor device having a deep recessed P+ junction is disclosed. The transistor device may comprise a gate and a source on an upper surface of the transistor device, and may include at least one doped well region, wherein the at least one doped well region has a first conductivity type that is different from a conductivity type of a source region within the transistor device and the at least one doped well region is recessed from the upper surface of the transistor device by a depth. The deep recessed P+ junction may be a deep recessed P+ implanted junction within a source contact area. The deep recessed P+ junction may be deeper than a termination structure in the transistor device. The transistor device may be a Silicon Carbide (SiC) MOSFET device.

Claim (Index 1):
A method of forming a transistor device having at least one sidewall and an upper surface, comprising:\n providing a gate and a source on the upper surface; providing at least one source region of a first conductivity type; providing at least one well region of a second conductivity type adjacent to the at least one source region, the at least one well region being recessed from the upper surface of the transistor device to a depth; and etching at least a portion of the upper surface of the transistor device to a recess depth as measured from the upper surface.
