Latest Patents

One of his latest patents is titled "Method and system for identifying etch end points in semiconductor circuit fabrication." This invention discloses a spectrometer system with unique wavelength resolution that enhances the relative positioning of the diffraction grating and detector. Additionally, it introduces a modified evolving windowed factor analysis-based method for detecting semiconductor etch end points, which is particularly well-suited for real-time monitoring and process control. The use of wavelength group selecting mask filters is also a key feature of this patent.

Another significant patent is related to "Analyzing spectrometric data." This spectrometric instrument includes a detector with detecting subarrays on small portions of the surface. Spectral data are acquired for selected subarrays at a first time for a drift standard and compared to a zero position to obtain first offset data. Similar data acquisition occurs at a second time to obtain second offset data. The offset data are utilized to determine a spectral shift for any subarray position at any selected time. This shift is then applied to a matrix model used for converting test data to compositional information.
