Patent ID: 8492849

Claim:
A high side semiconductor structure, comprising: a substrate; a first deep well and a second deep well formed in the substrate, wherein the first deep well and the second deep well have identical type of ion doping which is complementary with that of the substrate; a first active element and a second active element respectively formed in the first deep well and the second deep well; and a doped well formed in the substrate and between the first deep well and the second deep well, wherein the doped well, the first deep well and the second deep well are interspaced, and the type of ion doping of the first deep well and the second deep well are complementary with that of the doped well, wherein the substrate between the first active element and the second active element is active-element-free, the first active element is one type of an N-type and P-type metal oxide semiconductor, and the second active element is another type of the N-type and P-type metal oxide semiconductor.
