Claim Text:
1. A method of manufacturing a semiconductor device, comprising: forming a plurality of active patterns extending along a first direction and spaced apart from each other along a second direction across the first direction, on a substrate; forming a gate electrode across extending along the second direction to cross the plurality of the active patterns; forming a first contact disposed at one side of the gate electrode and extending along the second direction to be electrically connected to the plurality of the active patterns; forming a second contact connected to the gate electrode; and forming a third contact disposed at the side of the gate electrode and extending along the second direction from an end of the first contact, wherein the forming of the first contact comprises performing an exposure process using one photomask, the forming of the third contact comprises performing an exposure process using a photomask different from said one photomask, and wherein the third contact is formed such that a bottom surface of the third contact is disposed at a level in the device that is lower than that at which a top surface of the first contact is disposed.
