METHODS AND SYSTEMS FOR ENDPOINT DETECTION IN FORELINE OF CHAMBER CLEAN AND FORELINE CLEAN PROCESSES
Publication number: 20240063001Abstract: Systems and methods of monitoring a cleaning process for a deposition chamber are provided. A chamber cleaning source is activated to supply a cleaning agent to a deposition chamber and a foreline cleaning source disposed downstream of the deposition is activated to supply the cleaning agent to a foreline. The transmission recovery of an optical sensor disposed in the foreline is monitored. The optical sensor is disposed in the foreline at a location downstream of the foreline cleaning source. At least one of a foreline clean endpoint and a chamber clean endpoint is detected based on the monitored transmission recovery.Type: ApplicationFiled: August 14, 2023Publication date: February 22, 2024Inventors: Hongke Ye, Gordon Hill -
Patent number: 10228324Abstract: Presented herein are systems and methods for quantifying trace and/or ultra-trace levels of a species—for example, H2S or H2O—in a natural gas line. The systems and methods employ a tunable laser, such as a tunable diode laser, vertical-cavity surface-emitting laser (VCSEL), external cavity diode laser or a vertical external-cavity surface-emitting laser (VECSEL) or a tunable quantum cascade laser (QCL). The laser produces an output beam over a set of one or more relatively narrow, high resolution wavelength bands at a scan rate from about 0.1 Hz to about 1000 Hz. A natural gas sample comprising a trace level of a species of interest passes through a flow cell into which the output beam from the laser is guided. An optical detector receives light from the flow cell, producing a signal indicative of the absorption attenuation from which the concentration of the trace species is determined.Type: GrantFiled: July 25, 2017Date of Patent: March 12, 2019Assignee: MKS Instruments, Inc.Inventors: Peter Zemek, Robert M. Carangelo, Hongke Ye, Andrew Wright

Publication number: 20180266946Abstract: A system and method are disclosed for gas sensing over a wide tunable wavelength range provided by one or more quantum cascade lasers. A laser beam is generated within the wide tunable wavelength range, which is given by the sum of the wavelength ranges from the individual lasers. Gas sensing or detection is achieved by obtaining an infrared absorption spectrum for a sample contained in one or more cells having different path lengths for the laser beam.Type: ApplicationFiled: May 16, 2018Publication date: September 20, 2018Inventors: Petros A. Kotidis, Erik Deutsch, Hongke Ye, Alexander Mazurenko, Anish K. Goyal, Jeffrey S. Socha

Publication number: 20050168749Abstract: This invention relates to optical detection of vapors, in particular devices and methods for detection of vapor concentration and changes in vapor concentration using dynamic holography. The devices and methods employ a transducer which absorbs the vapor to be tested, thereby leading to a change in the transducer. The changes in the transducer cause a change in the optical path length of an image beam which is interacted with the transducer. Dynamic holography allows determination of the change in the dimensions and index of refraction of the transducer, and thus the change in the concentration of the vapor to be tested. The devices and methods of the invention are capable of testing a plurality of vapors by using a transducer array.Type: ApplicationFiled: July 2, 2003Publication date: August 4, 2005Inventors: Hongke Ye, Oyvind Nilsen, Dana Anderson, Victor Bright
