System And Method For Vacuum Chamber Leak Detection

View page
US Patent:
7590498, Sep 15, 2009
Filed:
Nov 30, 2007
Appl. No.:
11/948907
Inventors:
Sherk Chung - Emeryville CA, US
Mukund Chakravarthy Venkatesh - San Francisco CA, US
Paxton Ming Kai Chow - Walnut Creek CA, US
Jiuyi Cheng - Milpitas CA, US
Paul Tran - Sacramento CA, US
Joseph Raymond Monkowski - Danville CA, US
Assignee:
Pivotal Systems Corporation - Pleasanton CA
International Classification:
G01F 17/00
US Classification:
702 51
Abstract:
Leaks in a processing chamber, including “virtual leaks” resulting from outgassing of material present within the chamber, may be detected utilizing an optical emission spectroscopy (OES) sensor configured to monitor light emitted from plasma of a sample from the chamber. According to certain embodiments, gas introduced into the chamber by the leak may be detected directly on the basis of its optical spectrum. Alternatively, gas introduced by the leak may be detected indirectly, based upon an optical spectrum of a material resulting from reaction of the gas attributable to the leak. According to one embodiment, data from the OES sensor is received by a processor that is configured to compute a leak detection index. The value of the leak detection index is compared against a threshold to determine if a leak is detected. If the value of the index crosses the threshold, a notification of the existence of a leak is sent.

Method And Apparatus For Gas Flow Control

View page
US Patent:
20170010625, Jan 12, 2017
Filed:
Jul 8, 2016
Appl. No.:
15/206180
Inventors:
- Fremont CA, US
James Franklin - San Francisco CA, US
Jiuyi Cheng - Milpitas CA, US
Tao Ding - San Leandro CA, US
Andrey Shmakov - San Francisco CA, US
Travis Owens - Fremont CA, US
International Classification:
G05D 7/06
G01F 1/34
Abstract:
An apparatus for controlling the flow of a gas, containing a controllable valve, wherein the position of the valve and the gas pressure upstream of the valve are measured and used in conjunction with a first lookup table to determine the flow rate of the gas through the valve; and a flow restrictor upstream of the controllable valve, wherein the temperature of the flow restrictor and the gas pressure upstream and downstream of the flow restrictor are measured and used in conjunction with a second lookup table to determine the flow rate of the gas through the flow restrictor.
