Abstract

A semiconductor device comprises a source/drain diffusion area, and a first doped region. The source/drain diffusion area is defined between a first isolation structure and a second isolation structure. The source/drain diffusion area includes a source region, a drain region, and a device channel. The device channel is between the source region and the drain region. The first doped region is disposed along a first junction between the device channel and the first isolation structure in a direction from the source region to the drain region. The first doped region is separated from at least one of the source region and the drain region, and has a dopant concentration higher than that of the device channel. The semiconductor device of the present disclosure has low random telegraph signal noise and fewer defects.
