Disclosed is a method for forming patterns of a semiconductor device, which includes: arranging dense patterns to be transferred in a dense pattern region of a wafer; inserting a first dummy pattern for restricting pattern distortion of the dense patterns in an outside of the array of the dense patterns; inserting a first assist feature for restricting pattern distortion of the first dummy pattern in an inside of the first dummy pattern; inserting an array of second assist features for additionally restricting pattern distortion of the first dummy pattern in an outside of the first dummy pattern, thereto designing a pattern layout to be transferred onto the wafer; and forming an array of the dense patterns and the first dummy patterns by transferring the pattern layout onto the wafer through an exposure. |
