Abstract:
1. A packaging system for intercepting and capturing corrosive contaminants for the protection of IC wafers during fabrication, transport and storage phases, such wafers having surface components comprising bond pads, solder balls and interconnects which are susceptible to damage due to corrosion, mechanical shock or electrical static discharge, comprising: a) an enclosure having an interior volume and surrounding walls; b) a wafer stack located in the interior volume, the wafer stack comprising plural wafers, with space there between to allow air to flow therethrough; c) a sacrificial material located in the interior volume and having activated carbon and a metal, the sacrificial material intercepts and captures airborne molecular contaminants, the sacrificial material being dissipative to the static discharge, the sacrificial material located adjacent to at least one of the walls; d) a pouch, the pouch having a perforated wall, with a pouch interior, the sacrificial material comprising a film, the film being segments located the pouch interior.
