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 6):
A method comprising:\n measuring one or more spectral features of a pulsed light beam that is directed toward a substrate of a lithography exposure apparatus; receiving at least one lithography performance parameter associated with each sub-area of the substrate as the pulsed light beam interacts with that sub-area, 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; receiving the one or more measured spectral features of the pulsed light beam; analyzing the determined lithography performance parameter at each sub-area of the substrate; analyzing the one or more measured spectral features of the pulsed light beam; and based on these analyses: modifying a first spectral feature of the pulsed light beam, wherein modification of the first spectral feature takes into account the analysis of the one or more measured spectral features and wherein modification of the first spectral feature is based on a determination that the lithography performance parameter is outside an acceptable range; and maintaining a second spectral feature of the pulsed light beam to within a range of values of the second spectral feature while the first spectral feature of the pulsed light beam is being modified.
