Semiconductor structure

Abstract

A semiconductor structure includes a substrate, an insulating layer disposed on the substrate, an active layer disposed on the insulating layer and including a device region, and a charge trap layer in the substrate and extending between the insulating layer and the substrate and directly under the device region. The charge trap layer includes a plurality of n-type first doped regions and a plurality of p-type second doped regions alternately arranged and directly in contact with each other to form a plurality of interrupted depletion junctions.
