Abstract: The invention provides a chemical-mechanical polishing composition containing zirconia particles, a modifying agent that adheres to the zirconia particles, an organic acid, and water, as well as a method of using such a polishing composition to polish substrates and a method of using a polishing composition comprising zirconia particles, an organic acid, an oxidizing agent, and water to polishing substrates containing metal and oxide-based dielectric materials.

Abstract: The present invention provides chemical-mechanical polishing (CMP) methods for polishing a platinum and/or ruthenium containing substrate, and compositions suitable for use in the methods. The polishing compositions used with the methods of the invention, which contain alumina and at least one additive selected from the group consisting of a suppressor, a complexing agent, and an amino compound, allow for platinum and ruthenium to be polished. The methods of the invention provide for tailoring the relative removal rates of platinum, ruthenium, silicon oxide and silicon nitride.

Abstract: Transition metal complexes include a diazaphosphacycle of formula III and a transition metal. The phosphorus atom of the diazaphosphacycle is bonded to the transition metal and the diazaphosphacycle of formula III has the following structure where the variables have the values set forth herein.

Abstract: A phosphorus-containing compound is treated with at least one metal compound prior to fractional distillation to collect a purified fraction containing about 20 ppb or less arsenic. The purified phosphorus-containing compounds are useful for preparing electronic materials for electronic semiconductor manufacturing. Suitable metal compounds include salts, oxides and/or sulfides of iron, copper, nickel, cobalt, or zinc.

Abstract: A diazaphosphacycle may be synthesized by reacting a phosphine with a diimine and optionally one or more equivalents of an acid halide, a sulfonyl halide, a phosphoryl halide, or an acid anhydride in the substantial absence of O2 to form the diazaphosphacycle. The phosphine has the formula R1—PH2 where R1 is a substituted or unsubstituted aryl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted cycloalkyl group, or a substituted or unsubstituted ferrocenyl group.
