Zusammenfassung: | A novel pad in bottle (PIB) technology and PIB type advanced chemical mechanical planarization (CMP) copper or through silicon via (TSV) CMP compositions, systems, and methods are disclosed. The action of conventional polishing pad dimples is effected by high quality micro-sized polyurethane (PU) beads comparable to the size of the pores and dimples in the polishing pad. The cheaper non-porous and solid polishing pads are more economical and have been used to reduce electronic device manufacturing costs. The use of a PIB type Cu CMP slurry has benefits as compared to a non-PIB type Cu CMP slurry. Use of PIR-type Cu CMP has been observed that increases Cu removal rates at different applied downward forces and sliding speeds, decreased Cu wire depressions over Cu wire features of different sizes, and a slightly reduced average COF.
