Patent ID: 7589393

Claim:
A semiconductor structure of a high side driver, comprising: an ion-doped junction, 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 are separated but partially linked with each other and have the same ion-doped type, and a depletion region formed in the ion-doped junction having a continuous boundary at a partially-linked region of the first deep well and the second deep well; a first heavy ion-doped region, formed in the first deep well for connecting to a first high voltage, wherein the first heavy ion-doped region has the same ion-doped type as the first deep well; and a second heavy ion-doped region, formed in the second deep well for connecting to a second high voltage, wherein the second heavy ion-doped region has the same ion-doped type as the first deep well.
