Abstract
Several techniques are described for modulating the etch rate of a sacrificial light absorbing material (SLAM) by altering its composition so that it matches the etch rate of a surrounding dielectric. This particularly useful in a dual damascene process where the SLAM fills a via opening and is etched along with a surrounding dielectric material to form trenches overlying the via opening.
