  • Patent number: 12402390
    Abstract: A method of manufacturing a silicon carbide semiconductor power device is provided. In the method, the power device in high voltage (HV) region and CMOS device in the low voltage (LV) region are formed together, so the cost and time can be saved efficiently. First, a first drift layer is formed on a substrate, and then a shielding region is formed in the first drift layer. The shielding region includes a continuous region in the LV region. Then, a second drift layer is formed on the first drift layer. A pick-up region is formed in the second drift layer, wherein the pick-up region connects to the continuous region of the shielding region, and then NMOS and PMOS in the LV region and the power device in HV region are formed simultaneously. NMOS and PMOS are surrounded by the pick-up region and the continuous region, thereby minimizing body effect.
