Abstract
A semiconductor structure for suppressing hot clusters includes a substrate of a first dopant concentration, an epitaxial layer having a second dopant concentration smaller than the first dopant concentration and directly disposed on the substrate, a dopant gradient region disposed in the epitaxial layer and having a gradient decreasing from the substrate to the epitaxial layer, a shallow trench isolation disposed between a first element region and a second element region, and a shallow trench doping region surrounding the shallow trench isolation and near the dopant gradient region to suppress a hot cluster formed by the first element region to jeopardize the second element region.
