Filed:

Jan 19, 2001
Appl. No.:

09/764424
Inventors:

Dean L. Doty - Plano TX
Yan Xu - Houston TX
Stephen Chesters - Allen TX
Ben R. Hall - Mesquite TX
Roger Q. Petton - Dallas TX
Thomas P. Ross - Mesquite TX
Charles A. White - Red Oak TX

Assignee:

Air Liquide America, L.P. - Houston TX
International Classification:

E03B 100
US Classification:

137 9, 137597, 137607
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.

US Patent:

49642782, Oct 23, 1990
Filed:

Mar 6, 1989
Appl. No.:

7/318828
Inventors:

Horng-Yuan Wen - Brookfield IL
Hwa-Chi Wang - Downers Grove IL
Stephen Chesters - Chicago IL
Assignee:

American Air Liquide - Countryside IL
International Classification:

B01D 800
US Classification:

62 555
Abstract:

A method is described to remove condensible vapors in highly compressed gases without affecting the original particle spectra and concentrations. The vapors are separated from particles primarily through diffusion mechanism and collected on cold surfaces. Four important parameters are the length, the flow rate, the temperature, and the diffusion coefficients of the vapors to be removed. Important applications include sampling particles from high pressure gases and condensible vapor-free filling for ultra-pure cylinder gases.
