Abstract:
A semiconductor device may include plugs disposed in a zigzag pattern, interconnections electrically connected to the plugs and a protection pattern which is interposed between the plugs and the interconnections to selectively expose the plugs. The interconnections may include a connection portion which is in contact with plugs selectively exposed by the protection pattern. A method of manufacturing a semiconductor device includes, after forming a molding pattern and a mask pattern, selectively etching a protection layer using the mask pattern to form a protection pattern exposing a plug.
