Abstract

The US semiconductor industry uses 5–7 thousand pounds of arsine annually. Fifty to eighty percent of the arsine used becomes a waste product, which requires abatement. Traditional methods of abatement are reviewed with an emphasis on dry chemical scrubbing. A variety of dry chemical scrubbing materials were evaluated for arsine capacity, using activated carbon as the baseline for comparison. A proprietary mixed oxide composition, employing copper oxide as the active ingredient was identified as having high capacity and efficiency. Disposal and possible reclamation options are discussed.

4 Gallons is typically a fluid measurement. Dry scrubber media like activated carbon, are sold commercially on a volume, rather than a weight basis. In addition, disposal costs are related to volume; i.e., number of 55 gallon drums. The bulk density of activated carbon is 0.56 g/cc.Google Scholar
