Abstract:
1. A semiconductor device, comprising: a source region and a drain region, having a first conductivity type and disposed in a substrate; an isolation structure, disposed between the source region and the drain region; a gate structure, disposed on the substrate between the source region and the drain region; a conductive layer, disposed on the substrate, at least extending from above the source region to above the isolation structure, and electrically connected to the source region, wherein the substrate comprises a first area and a second area, a border curvature of the source region in the second area is greater than a border curvature of the source region in the first area, and a width of the a portion of the conductive layer covering the isolation structure in the second area is greater than a width of another portion of the conductive layer covering the isolation structure in the first area.
