Abstract:
A photolithography method includes producing, from an optical source, a pulsed light beam; and scanning the pulsed light beam across a substrate of a lithography exposure apparatus to expose the substrate with the pulsed light beam including exposing each sub-area of the substrate with the pulsed light beam. A sub-area is a portion of a total area of the substrate. For each sub-area of the substrate, a lithography performance parameter associated with the sub-area of the substrate is received; the received lithography performance parameter is analyzed, and, based on the analysis, a first spectral feature of the pulsed light beam is modified and a second spectral feature of the pulsed light beam is maintained.

Claim (Index 13):
A photolithography apparatus comprising:\n a spectral feature selection system that optically interacts with a pulsed light beam; a metrology apparatus configured to determine at least one lithography performance parameter at each sub-area of a substrate, in which a sub-area is a portion of a total area of the substrate and in which a lithography performance parameter is a characteristic associated with the substrate or with the pulsed light beam as it interacts with the substrate; and a control system connected to the spectral feature selection system and the metrology apparatus, and configured to, at each substrate sub-area:\n receive the determined lithography performance parameter; \n analyze the determined lithography performance parameter; and \n based on the analysis of the determined lithography performance parameter:\n modify a wavelength of the pulsed light beam by sending a first signal to the spectral feature selection system, wherein the modification of the wavelength causes a change in a bandwidth of the pulsed light beam; and \n maintain the bandwidth of the pulsed light beam to within an acceptable range of values while the wavelength is being modified.
