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 17):
A system for chemical mechanical planarization a semiconductor substrate comprising at least one surface containing elemental silicon, comprising:\n the semiconductor substrate; a polishing pad; and a polishing composition comprising:\n abrasive particles ranging from 0.01 wt. % to 15 wt. %; \n a compound to enhance removal rate of films comprising elemental silicon ranging from 0.001 wt. % to 0.5 wt. %; and \n liquid carrier; and \n pH of the polishing composition is between 2 and 12; \n wherein \n 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 \n the compound to enhance removal rate of films comprising elemental silicon is selected from a group consisting of isothiazolinone and derivatives, thiazolinone and derivatives, imidazolidine and derivatives, pyrozolidine and derivatives, imidazole and derivatives, pyrazole and derivatives, thiazole and derivatives, isothiazole and derivatives, thiazolidine and derivatives, isothiazolidine and derivatives, dithiolane and derivatives, triazole and derivatives, tetrazole and derivatives, thiadiazole and derivatives; acetone, benzophenone, acetophenone, acetylacetone, butanol, 3-hydroxybutanal, p-nitrobenzenzaaldehyde, cinnamaldehyde, vanillin, and combinations thereof; \n wherein the semiconductor substrate is in contact with the polishing composition and the pad.
