摘要: In a method and apparatus for plasma stripping a polymer photoresist coating from a semiconductor substrate, positively charged species are removed from an activated gas flow before the gas flow is brought into contact with the coating to strip the coating from the substrate. The positively charged species may be removed by bringing the activated gas into contact with a grounded conducting surface to discharge the positively charged species, or by passing the activated gas through a negatively charged electrostatic filter to filter out positively charged species. The removal of positively charged species from the gas flow reduces or eliminates build up of positive charge on an outer surface of the photoresist coating so as to avoid driving mobile positively charged ions from the photoresist into the substrate, thereby avoiding contamination of the substrate.

摘要: A portable decal stripping tool particularly adapted for the quick removal of adhesive decals from an automotive surface and comprising a decal stripper attachment for a soldering iron including an elongate shaft with a head portion secured thereto adapted to removably engage and support a razor blade. The decal stripper attachment is constructed of heat conductive material which facilitates elevation of the temperature of the razor blade secured therein so that it will slide under and remove a decal by melting the adhesive securing it to an automobile surface or the like.
