Mercury process gold ballbond removal apparatus

摘要

A method and apparatus for reducing the risk of environmental contamination from mercury spillage during carry over between processing tanks during the gold ball bond removal process by providing a self-contained, compact, environmentally safe system for use with toxic chemicals and liquids. The present invention provides a self-contained, integrally molded enclosure upper and lower chambers separated by a partition. The partition has a plurality of stations integrally formed therein, each of which is capable of containing a chemical liquid. The method comprises dipping a slide containing the semiconductor chip first into a toxic liquid, then into a first decontamination station and finally into a second decontamination station.
