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 14):
The polishing method of  claim 11 , wherein the semiconductor substrate further comprises at least one surface containing silicon oxide, silicon nitride or combinations thereof; and the polishing composition further comprises from 0.1 ppm to 0.5 wt. % of (i) a polyacrylic acid or its salts with molecular weight ranging between 500 and 100,000; (ii) an additive having a functional group selected from the group consisting of organic carboxylic acids and salts thereof, amino acids and salts thereof, amidocarboxylic acids and salts thereof, N-acylamino acids and salts thereof, organic sulfonic acids and salts thereof; organic phosphonic acids and salts thereof; polymeric carboxylic acids and salts thereof; polymeric sulfonic acids and salts thereof; polymeric phosphonic acids and salts thereof; arylamines, aminoalcohols, aliphatic amines, heterocyclic amines, hydroxamic acids, substituted phenols, sulfonamides, thiols, polyols having hydroxyl groups, and combinations thereof; or combinations of (i) and (ii);\n wherein removal rate selectivity between elemental silicon and silicon oxide or silicon nitride is tunable between 0.1 to 110.
