Dear all, Could someone tell me whether Cl-containing plasma attack Mo or not? If there is a reference that directly talk about that, would you please let me know? My goal is to have a plasma that would attack silicon, silicon nitride, and silicon oxide, but would not attack Mo, at least not by RIE. Would Cl-containing plasma achieve this purpose? I do not see any reference that talk about etching Mo with Cl-containing plasma. Thanks for your help. Yours sincerely, Isaac Chan Ph.D. Candidate Dept.
