Patent number: 12007428Abstract: Embodiments of the present invention provide systems and methods for multidimensional parts average testing for testing devices and analyzing testing results to detect outliers according to embodiments of the present invention. The testing can include calculating multivariate (e.g., bivariate) statistics using delta measurements of like devices, a ratio of measurements, or principal component analysis that identifies eigenvectors and eigenvalues to define meta parameters, for example. Raw test result data can be converted to residual space and robust regression can be performed to prevent outlier results from influencing regression, thereby reducing overkill advantageously.Type: GrantFiled: October 8, 2021Date of Patent: June 11, 2024Assignee: ADVANTEST CORPORATIONInventors: Kenneth Butler, Ira Leventhal, Constantinos Xanthopoulos, Alan Hart, Brian Buras, Keith Schaub

Patent number: 11940487Abstract: An apparatus for thermal control of a device under test (DUT) includes a cooling structure operable to provide cooling, the cooling structure operable to inlet cooling material via an inlet port thereof and operable to outlet cooling material via an outlet port thereof, a variable thermal conductance material (VTCM) layer disposed on a surface of the cooling structure, and a heater layer operable to generate heat based on an electronic control, and wherein the VTCM layer is operable to transfer cooling from the cooling structure to the heater layer. A thermal interface material layer is disposed on the heater layer. The thermal interface material layer is operable to provide thermal coupling and mechanical compliance with respect to the DUT. The apparatus includes a compression mechanism for providing compression to the VTCM layer to vary a thermal conductance of the VTCM layer. The compression mechanism is also for decoupling the VTCM layer from the heater layer.Type: GrantFiled: January 9, 2023Date of Patent: March 26, 2024Assignee: Advantest Test Solutions, Inc.Inventors: Samer Kabbani, Kazuyuki Yamashita, Ikeda Hiroki, Ira Leventhal, Mohammad Ghazvini, Paul Ferrari, Karthik Ranganathan, Gregory Cruzan, Gilberto Oseguera
