Abstract: A system and method of manufacturing a semiconductor device lithographically and an article of manufacture involving a lithographic double patterning process having a dye added to either the first or second lithographic pattern are provided. The dye is used to detect the location of the first lithographic pattern and to directly align the second lithographic pattern to it. The dye may be fluorescent, luminescent, absorbent, or reflective at a specified wavelength or a given wavelength band. The wavelength may correspond to the wavelength of an alignment beam. The dye allows for detection of the first lithographic pattern even when it is over coated with a radiation sensitive-layer (e.g., resist).
