发明名称 METHOD FOR USING A HARD MASK FOR CRITICAL DIMENSION GROWTH CONTAINMENT
摘要 <p>A method for containing the critical dimension growth of the feature on a semiconductor substrate (56) includes placing a substrate with a hard mask (52) comprised of a reactive metal or an oxidized reactive metal in a chamber and etching the wafer. The method further includes using a hard mask which has a low sputter yield and a low reactivity to the etch chemistry of the process.</p>
