Abstract:
1. A method of manufacturing a semiconductor device using a scanner, wherein the scanner is capable of realizing a minimum pitch, wherein the minimum pitch is the smallest possible pitch for the scanner, the method comprising: providing a semiconductor substrate; forming a first layer over the semiconductor substrate; forming a second layer over the first layer; patterning the second layer to form a plurality of second layer patterns; patterning the first layer to form a plurality of first layer patterns, wherein a line width of the first layer patterns is greater than a line width of the second layer patterns, and each second layer pattern is located approximately over the center of a corresponding first layer pattern; performing a tone reversal to form a reversed tone for the second layer patterns; and etching the first layer patterns using the reversed tone as a mask, wherein the etched first layer patterns have a final pitch size, and wherein the final pitch is smaller than the minimum pitch.
