Abstract

An automated filling system for introducing crushed polysilicon fragments into shipping bags without significant contamination positions a freely suspended energy absorber into a freely suspended bag of non-contaminating material prior to filling, and following filling, the energy absorber is removed, and the bag is sealed. The system can replace manual packaging which has been required for semiconductor applications.
