PFA Coating Eliminates Metal Contamination
Process: Photoresist manufacturing Location: Northeastern U.S.A. History: Photoresists and ancillary chemicals are produced at this facility. Semiconductor manufacturers are the end users. This primarily batch operation produces product that is shipped in 1- to 55-gallon containers. The level of product purity required, always a concern with chemicals destined for the semiconductor industry, has become increasingly more stringent. Ion contaminat
