The invention can provide a method of processing a substrate using multi-pitch scatterometry targets (M-PSTs) for de-convolving lithographic process parameters during Single-Patterning (S-P), Double-Patterning (D-P) procedures, and Double-Exposure (D-E) procedures used to control transistor structures. The M-PSTs) can have critical dimension (CD) and sidewall angle (SWA) sensitivity to exposure focus variations, exposure dose variations, and post exposure bake (PEB) temperature variations. In addition, the variation can be de-convolved so that the individual measurement process variable contributor can be identified.
