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 1):
An apparatus comprising:\n a spectral feature selection system that optically interacts with a pulsed light beam; a measurement system configured to measure one or more spectral features of the pulsed light beam; a metrology apparatus configured to determine at least one lithography performance parameter for 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, the measurement system, and the metrology apparatus, and configured to, for each substrate sub-area:\n receive the determined lithography performance parameter from the metrology apparatus and receive the one or more measured spectral features of the pulsed light beam from the measurement system; \n analyze the determined lithography performance parameter for each sub-area of the substrate and analyze the one or more measured spectral features of the pulsed light beam; and \n based on these analyses:\n send a first signal to the spectral feature selection system to modify a first spectral feature of the pulsed light beam, wherein the modification of the first spectral feature takes into account the analysis of the one or more measured spectral features and wherein the first signal is sent based on a determination that the lithography performance parameter is outside an acceptable range; and \n maintain a second spectral feature of the pulsed light beam to within a range of values of the second spectral feature by sending a second signal to the spectral feature selection system while the first spectral feature of the pulsed light beam is being modified.
