Abstract
Proposed are a semiconductor device and a method of manufacturing the same, in which a first device isolation region includes a Pre-DTI region and a DTI region, wherein the DTI region is configured to be physically distinguishable by having an extension part with a substantially flat outer surface and a connection part with an outer surface including a concave and convex embossed portion so that an air gap in the first device isolation region is prevented from being formed in an asymmetric shape and is prevented from being externally exposed in a subsequent process.
