ABSTRACT:
A semiconductor power device includes a device feature layer, a substrate contact layer and a voltage-sustaining layer between them. The voltage-sustaining layer includes alternating semiconductor and high permittivity dielectric regions, where each region extends from the device feature layer to the substrate contact layer. Due to the flux of charges transported dominantly through the dielectric regions, the whole voltage-sustaining layer behaves like a semiconductor having a much higher electric permittivity than that of the semiconductor itself, so that the field produced by the ionized impurities of the semiconductor regions can be much higher than that of the conventional one for sustaining the same reverse voltage, and the specific on-resistance can be lower than that of the conventional one. The use of high permittivity dielectric regions can also be applied to the charge-balance structure, i.e., to COOLMOST.
