Semiconductor device having DC structure
Abstract:
A semiconductor device includes an interlayer insulating layer on a substrate, and a direct contact (DC) structure vertically penetrating the interlayer insulating layer and contacting the substrate, the DC structure including a DC hole exposing the substrate, an insulating DC spacer on an inner wall of the DC hole, and a conductive DC plug on the DC spacer and filling the DC hole, the DC plug including a lower DC plug and an upper DC plug on the lower DC plug, the lower DC plug having a smaller horizontal width than that of the upper DC plug.
