Patent ID: 7862638

Claim:
A gas supply system that supplies a corrosive gas to a semiconductor manufacturing apparatus via a gas supply flow passage, the gas supply system comprising: a gas filter that removes at least solid-state metal particles contained in the gas flowing through said gas supply flow passage; and a metal component remover that removes a volatile metal component contained in a gas distributed through said gas supply flow passage by liquefying the volatile metal component, wherein said metal component remover is disposed downstream of said gas filter in said gas supply flow passage, said metal component remover includes a gas flow passage being part of said gas supply flow passage and a flow passage cooling means for cooling said gas flow passage from an outside by distributing a coolant on an outside of said gas flow passage, said gas flow passage in said metal component remover is divided into an inflow-side flow passage and an outflow-side flow passage, both passages disposed along a vertical direction, the gas flows in from an upper side area of said inflow-side flow passage, a lower portion of said inflow-side flow passage communicates with a liquid collection chamber, and a lower portion of said outflow-side flow passage communicates with said liquid collection chamber with the gas flowing out through an upper side area of said outflow-side flow passage.
