Abstract

A method and apparatus for generating gas for a processing system is provided. In one embodiment, an apparatus for generating gas for a processing system includes an unitary, isolatable, transportable canister having a plurality of first spacing elements, a plurality of second spacing elements and a solid material disposed within the canister. The spacing elements have different mean diameters. The solid material is adapted to produce a gas vapor when exposed to a temperature above a predetermined level at a predetermined pressure. In another embodiment, an apparatus for generating gas includes a gas source coupled to a processing chamber by a first gas line. A canister is coupled in-line with the first gas line and contains a solid material that produces a process gas when heated. A heater is disposed between the gas source and the canister to heat gas flowing into the canister.
