Abstract:
1. A method for processing substrates to manufacture semiconductor structures thereon, comprising: analyzing at least one first processing parameter of a track for processing a substrate, thereby yielding at least one first throughput rate of the track, wherein the first processing parameter comprises at least one of a processing time for forming an adhesive layer over the substrate, a processing time for forming a photoresist layer over the substrate, a processing time for cooling the substrate, a processing time for baking the substrate and a processing time for developing the photoresist layer; analyzing at least one second processing parameter of a scanner for processing the substrate, thereby yielding at least one second throughput rate of the second apparatus, wherein the second parameter comprises at least one of a range of overlay, a range of focus and a range of energy, wherein the step of analyzing the second processing parameter second includes: comparing the first throughput rate and the second throughput rate, thereby yielding at least one comparison result for processing the substrate; adjusting the at least one second processing parameter of the scanner if the at least one first throughput rate is substantially different from the at least one second throughput rate; and forming semiconductor structures on a substrate in accordance with the at least one first processing parameter of the track and the adjusted second processing parameter of the scanner.
