Abstract:
A chemical mechanical planarization for indium phosphide material is provided in which at least one opening is formed within a dielectric layer located on a substrate. An indium phosphide material is epitaxially grown within the at least one opening of the dielectric layer which extends above a topmost surface of the dielectric layer. The indium phosphide material is planarized using at least one slurry composition to form coplanar surfaces of the indium phosphide material and the dielectric layer, where a slurry composition of the at least one slurry composition polishes the indium phosphide material selective to the topmost surface of the dielectric layer, and includes an abrasive, at least one pH modulator and an oxidizer, the at least one pH modulator including an acidic pH modulator, but lacks a basic pH modulator, and where the oxidizer suppresses generation of phosphine gas.

Claim (Index 1):
A slurry composition for planarizing an indium phosphide material, the slurry composition comprising:\n an abrasive, at least one pH modulator and an oxidizer, the at least one pH modulator comprising at least one of an acidic pH modulator and a basic pH modulator, wherein the oxidizer suppresses generation of phosphine gas.
