  • Abstract
    Lateral Double Diffusion MOSFET is widely used due to its excellent properties. However, the contradictory between on-resistance and breakdown voltage (BV) is proved to be the technical bottleneck of optimizing power devices. On one hand, technologies such as REduce SURface Filed (RESURF), Field Plate and Variation of Lateral Doping are applied to enhance the breakdown characteristics of power devices. On the other hand, due to the limits of silicon material, to reach a higher breakdown voltage, the on-resistance must be set higher. The proposed structure, comparing with conventional structure, exhibits a higher breakdown voltage property while keeping the on-resistance invariant.
