Abstract: To provide an SiC MOSFET device with low characteristic on-resistance and a manufacturing method thereof.SOLUTION: A device has an N+region extending in one direction (Y direction), a P well region, and a JFET region, and has a P+region extending in an orthogonal direction (X direction) and a source contact. A polysilicon gate of the device covers a JFET region and ends over the P well region, and minimizes the electric field at the edge of the polysilicon gate. A current flows vertically from the drain contact at the bottom of the structure to the JFET region, then passes laterally in the X direction through a storage region and flows through a MOSFET channel to the adjacent N+region. The current flowing out of the channel then flows in the Y direction along the N+region and is collected by a source contact and final metal.SELECTED DRAWING: Figure 1A
