Patent number: 10302607Abstract: Analysis of chemically samples using gas chromatography (GC) separation with vacuum ultra-violet spectroscopy detection is described. One technique focuses on assigning a specific analysis methodology to each constituent in a sample. Constituents can elute from the GC by themselves or with other constituents, in which case a deconvolution is done using VUV spectroscopic data. In an exemplary embodiment, each constituent may be specifically included in an analysis method during a setup procedure, after which the same series of analyses are done on subsequent sample runs. The second approach essentially integrates an entire chromatogram by first reducing it into a series of analysis windows, or time slices, that are analyzed automatically. The analysis at each time slice determines the molecular constituents that are present as well as their contributions to the total response. Either approach can be used to quantify specific analytes or to do bulk classification.Type: GrantFiled: June 7, 2016Date of Patent: May 28, 2019Assignee: VUV Analytics, Inc.Inventors: Phillip Walsh, Dale A.

Patent number: 8867041Abstract: An optical metrology apparatus for measuring nanoimprint structures using Vacuum Ultra-Violet (VUV) light is described. Focusing optics focus light onto the sample and collect the light reflected from the sample so as to record an optical response from nanoimprint structures on the sample, wherein the nanoimprint structures have an orientation that varies over a surface of the sample. A sample stage is configured to support the sample. At least one computer is connected to the metrology instrument and the sample stage and is configured to run a computer program which causes the sample stage to rotate the sample so as to present multiple different locations on the sample to the optical metrology instrument such that the orientation of the nanoimprint structures at the multiple different locations remains fixed with respect to a plane of the focusing optics of the metrology instrument in order to eliminate polarization effects.Type: GrantFiled: January 15, 2012Date of Patent: October 21, 2014Assignee: Jordan Valley Semiconductor LtdInventors: Phillip Walsh, Jeffrey B.

Patent number: 8564780Abstract: A method and apparatus is disclosed for using below deep ultra-violet (DUV) wavelength reflectometry for measuring properties of diffracting and/or scattering structures on semiconductor work-pieces is disclosed. The system can use polarized light in any incidence configuration, but one technique disclosed herein advantageously uses un-polarized light in a normal incidence configuration. The system thus provides enhanced optical measurement capabilities using below deep ultra-violet (DUV) radiation, while maintaining a small optical module that is easily integrated into other process tools. A further refinement utilizes an r-? stage to further reduce the footprint.Type: GrantFiled: July 28, 2010Date of Patent: October 22, 2013Assignee: Jordan Valley Semiconductors Ltd.Inventors: Phillip Walsh, Dale Harrison
