An embedded semiconductor device which a logic region and the memory region are planarized with planarization resistance patterns and a method of manufacturing the same are disclosed. The embedded semiconductor device includes a substrate, gates formed on the substrate, source/drain regions formed on both sides of the gates in the substrate, a first interlayer dielectric (ILD) layer which covers the gates and the source/drain regions, first via plugs which vertically penetrate the first ILD layer and are selectively connected to the source/drain regions, capacitors and second via plugs selectively connected to the first via plugs, a second ILD layer that fills the space between the capacitors and the second via plugs, planarization resistance patterns formed on the second ILD layer, a third ILD layer formed on the second ILD layer and the planarization resistant patterns, and third via plugs which vertically penetrate the third ILD layer, and are selectively connected to a top electrode of the capacitors and the second via plugs.
