Patent ID: 7452816

Claim:
A semiconductor processing method, comprising: providing a semiconductor substrate comprising an array of capacitor openings formed within a material, the substrate comprising a capacitor electrode metal layer received over the material internally and externally of the openings and lining the openings, an organic photoresist layer received over the capacitor electrode metal layer within the openings and externally of the openings; and chemical mechanical polishing the organic photoresist layer and the capacitor electrode metal layer at least to the material using a polishing pad and an aqueous slurry of pH of less than or equal to 4.0 comprising abrasive particles comprising an individual particle size of less than or equal to 100 nanometers and at a particle concentration of less than or equal to 20% by weight effective to achieve a removal rate of the organic photoresist layer of at least 500 Angstroms per minute.
