Colloidal silica dispersions are used by the semiconductor materials industry as polishing agents to achieve mirror-like surface finish on substrates of silicon, GaAs, InP and other semiconductor materials. In these applications, a "perfect surface" is required for manufacture of integrated circuits, power devices and other semiconductor components.
Chemical mechanical planarization is an important step in the wafer treatment process and part of the manufacturing process of silicon wafers.
