Abstract:
1. A mask to manufacture a semiconductor device comprising: a first mask pattern on a first side of the mask, the first mask pattern including a light-blocking pattern comprising (i) a plurality of cell patterns corresponding to structures in the device and (ii) a light-blocking fine auxiliary pattern within a light-transmitting region between cell patterns in said light-blocking pattern at locations corresponding to where a bridge may form on the device, wherein the light-blocking fine auxiliary pattern is disconnected from the cell patterns and is completely surrounded by the light-transmitting region; and a second mask pattern on a second side of the mask, the second mask pattern including a light-transmitting fine auxiliary pattern within a light-blocking region, the light-transmitting fine auxiliary pattern being disposed at a position corresponding to a position of the light-blocking fine auxiliary pattern to facilitate an overlapping exposing process wherein the second mask has an opposite tone from the first mask pattern, and wherein the second mask pattern is disposed at a position horizontally-translated from a position of the first mask pattern.
