The disclosure relates to a π type trench gate silicon carbide MOSFET device and a fabrication method thereof. To protect a trench gate oxide layer without increasing a channel resistance and process complexity, a second conductivity type of heavily doped deep well inserted with double gate trenches along the sidewalls of deep well is designed. The deep well is connected to the source metal directly.

An interlayer dielectric layer is deposited above the conductive dielectric polysilicon layers and extends outward separately to cover a part of the source region. A smaller cell pitch can be achieved by controlling the spacing between the first and the second trench gate, thereby increasing the channel density and reducing the channel resistance.
