Abstract
A semiconductor device includes a substrate, a gate structure, a source/drain pattern, first and second interlayer insulating layers, a first via plug connected to the source/drain pattern, and an etch stop structure layer, which may include a plurality of etch stop layers sequentially stacked. The etch stop structure layer may have a structure in relation to other components that improves aspects of the semiconductor device.
