Method of abrading silicon substrate

摘要

A method of abrading a portion of a silicon substrate includes fluidizing abrasive particulate material with a first gas within a storage container, combining the gas fluidized abrasive particulate material with a stream of a second gas to provide a stream of the gas fluidized abrasive particulate material, and directing the stream of the gas fluidized abrasive particulate material at the silicon substrate to abrade the portion of the silicon substrate.
