Abstract:
Chemical Mechanical Planarization (CMP) polishing compositions comprising abrasive particles and additives to boost removal rates of films comprising elemental silicon such as poly-silicon and Silicon-Germanium.

Claim (Index 1):
A polishing composition comprising:\n abrasive particles ranging from 0.01 wt. % to 15 wt. %; a compound to enhance removal rate of films comprising elemental silicon ranging from 0.001 wt. % to 0.5 wt. %; liquid carrier; and pH of the polishing composition is between 2 and 12; wherein the abrasive particles are selected from the group consisting of fumed silica, colloidal silica, fumed alumina, colloidal alumina, cerium oxide, ceria-silica composite particles, titanium dioxide, zirconium oxide, polystyrene, polymethyl methacrylate, mica, hydrated aluminum silicate, and combinations thereof; and the compound to enhance removal rate of films comprising elemental silicon is selected from the group consisting of (i) heterocycle carbon compound comprising sulfur or nitrogen or both sulfur and nitrogen as heteroatoms and a carbonyl group attached to the ring structure; (ii) heterocycle carbon compound comprising sulfur or nitrogen or both sulfur and nitrogen as heteroatoms; (iii) an aldehyde or a ketone compound; and combinations thereof.
