Abstract
A method for making high density foam semiconductor polishing pads and belts with controlled, reproducible microcellular structure by mechanical frothing. The method involves agitating a liquid polymer resin at a controlled temperature and pressure in order to produce a stable froth. Next, the resin froth is metered under pressure to a mix head where it is typically combined with a desired amount of curative before being injected or poured into a mold.
