Filed:

Dec 31, 2003

Appl. No.:

10/750309

Inventors:

Christopher M. Bailey - Pleasanton CA, US
Michael S. Boger - Palo Alto CA, US

Assignee:

The BOC Group, Inc. - Murray Hill NJ

International Classification:

F04B 25/00
F04B 39/00
C23C 14/00

US Classification:

417248, 417313, 118 50, 118715, 118719

Abstract:

The present invention is an apparatus and method for controlling pressure, pumping a vacuum and providing abatement for a plurality of vacuum processing chambers. The system may be used in semiconductor manufacture. Multiple vacuum processing chambers are exhausted by turbo pumps into a common abatement chamber, which is maintained at sub-atmospheric pressure by a backing pump. Pressure in the processing chambers is independently controlled. The internal volume of the abatement device provides a buffer that reduces the effect of pressure changes in one processing chamber affecting pressure in the other chambers.

International Classification:

B01D 57/02

US Classification:

204450, 204451, 204454, 204600, 204601

Abstract:

A flow controller which uses a combination of hydrostatic pressure and electroosmotic flow to control the flow of a fluid. A driving fluid () whose flow rate is dependent on both hydrostatic pressures and electroosmotic flow can be used (a) directly as a working fluid in an operable device, for example a chromatograph, or (b) to displace a working fluid () from a storage container () into an operable device (), or both (a) and (b). The driving fluid () can be composed of one or more fluids. Part or all the driving fluid () is passed through an electroosmotic device () so as to increase or decrease the flow rate induced by hydrostatic pressure.

Appl. No.:

11/200369

Inventors:

Phillip H. Paul - Livermore CA, US
Don Wesley Arnold - Livermore CA, US
Christopher G. Bailey - Pleasanton CA, US

Assignee:

Eksigent Technologies, LLC - Dublin CA

International Classification:

G05D 7/06

US Classification:

204600, 204450

Abstract:

Electroosmotic flow controllers and methods of fluid flow control are described. The invention uses an electroosmotically generated flow component in conjunction with a pressure driven flow component to modulate fluid flow. The devices and methods of the invention may include salt bridges for making electrical connection between a power supply and a channel filled with a porous dielectric material and a fluid. Embodiments including flow controllers and flow splitters are described as is their use in a variety of fluid handling applications.
