Abstract:

Provided are apparatuses and methods for mixing gases. The apparatuses are suitable for use in the manufacture of an electronic device. The apparatuses include a gas mixing manifold. A first, bulk gas source is connected to introduce a flow of a first gas to the manifold. A second gas source is connected to introduce a flow of a second gas to the manifold. The first and second gases are mixed in the manifold, thereby forming a gas mixture. A conduit is connected to one or more point of use for introducing a flow of the gas mixture thereto. The present invention is particularly applicable in the semiconductor manufacturing industry.
