ABSTRACT:
Scavengers for removing acidic or corrosive gaseous components from semiconductor process effluents comprising a metallic macromer comprising a coordinated complex of (i) metal coordination atoms linked to (ii) oxomeric moieties selected from the group consisting of carbonate, sulfite, carboxylate, and silicate, and methods for synthesizing these scavengers. A method for cleaning an exhaust gas containing least one corrosive or acidic gaseous component selected from the group consisting of hydrogen halide, chlorine, boron trihalide, thionyl chloride, and tungsten hexafluoride, which comprises contacting the exhaust gas with the metallic macromer scavenger compositions.
