Patent ID: 7040970

Claim:
An adjustable polishing fluid dispensing mechanism for use in chemical mechanical planarization of a semiconductor wafer utilizing a polishing pad, said polishing fluid dispensing mechanism comprising: a spray nozzle, wherein said spray nozzle includes a mounting member, a main body connected to said mounting member, and a spray tip extending from said main body and said spray tip having an aperture formed therethrough for dispensing a spray of a polishing fluid; a carrier member, said mounting member being flexibly connected to said carrier member and said flexible connection between said carrier member and said mounting member provides said spray nozzle with rotational movement relative to said carrier member; a lateral actuating mechanism, said lateral actuating mechanism operatively connected to said carrier member, and said lateral actuating mechanism configured to provide lateral translation of said carrier member relative to said polishing pad; a vertical actuating mechanism, said vertical actuating mechanism operatively connected to said carrier member, and said vertical actuating mechanism configured to provide vertical translation of said carrier member relative to said polishing pad; and a longitudinal actuating mechanism, said longitudinal actuating mechanism operatively connected to said carrier member, and said longitudinal actuating mechanism configured to provide longitudinal translation of said carrier member relative to said polishing pad.
