Latest Patents

Barker's latest patents include innovative methods and compositions for insulator and metal chemical mechanical planarization (CMP). One of his key inventions involves a method of polishing a wafer in a carrier using a polishing pad. This method controls the ratio of platen speed to carrier speed (PS to CS) within a specific range. The first polishing step is conducted with a PS to CS ratio ranging from about 150:1 to about 1:150, followed by a second polishing step with a platen speed of about 0 to 20 rpm while maintaining the carrier speed used in the first step. This innovative approach maximizes the clearing of residual material from a patterned wafer surface during polishing.
