Patent ID: 7787977

Claim:
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, at least two of a first scan speed corresponding to the range of overlay, a second scan speed corresponding to the range of focus and a third scan speed corresponding to the range of energy, selectin minimum value from the first scan speed, the second scan speed and the third scan speed, analyzing the minimum value, thereby yielding a processing time of the scanner, and dividing a time period by the processing time of the scanner, thereby yielding the second throughput rate; 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.
