Abstract
An optically tuned SLAM (Sacrificial Light-Absorbing Material) may be used in a via-first dual damascene patterning process to facilitate removal of the SLAM. The monomers used to produce the optically tuned SLAM may be modified to place an optically sensitive structure in the backbone of the SLAM polymer. The wafer may be exposed to a wavelength to which the SLAM is tuned prior to etching and/or ashing steps to degrade the optically tuned SLAM and facilitate removal.
