Publication number: 20240142517Abstract: In an optical carrier injection method, a pulsed optical beam having pulse duration of 900 fs or lower is applied on a backside of a substrate of an integrated circuit (IC) wafer or chip, and is focused at a focal point in an active layer on a frontside of the substrate. Photons of the optical beam are absorbed at the focal point by nonlinear optical interaction(s) to inject carriers. The pulsed optical beam may be applied using a fiber laser in which the fiber is doped with Yb and/or Er. An output signal may be measured, comprising an electrical signal or a light output signal produced by the IC wafer or chip in response to the injected carriers. By repeating the applying, focusing, and measuring over a grid of focal points in the active layer, an image of the IC wafer or chip may be generated.Type: ApplicationFiled: January 11, 2024Publication date: May 2, 2024Inventors: Thomas F. Kent, Jeffrey A. Simon

Publication number: 20230377127Abstract: To validate an integrated circuit (IC), the IC is imaged by scanning an optical beam over the IC to optically inject carriers and measuring an output signal generated by the IC in response to the injected optical carriers. A comparison between the image of the IC and a reference image is computed, and suspect regions of the IC are identified based on the comparison. The reference image may be an image of a reference IC. In another approach, images of training ICs are acquired, and a deep learning algorithm is trained to transform corresponding training IC layouts to the images of the training ICs. The trained deep learning algorithm then transforms a layout of the IC to generate the reference image. The comparison may be computed by computing an error metric for each region corresponding to a standard cell in the reference image.Type: ApplicationFiled: May 17, 2023Publication date: November 23, 2023Inventors: Thomas F.

Publication number: 20230194599Abstract: In an approach to inspecting integrated circuits, a system includes a first detection system and a second detection system for measuring electroluminescent (EL) images from a device under test (DUT); and a controller. The controller is configured to: measure EL emissions from the DUT with the first and the second detection systems to obtain a first and a second EL test data; compare the first and the second EL test data to a reference model of a reference device, the reference model developed based on measured EL reference data, synthetic EL reference data, or a combination thereof obtained from the reference device or a reference design of the reference device; and determine whether the DUT is in accordance with the reference device, based at least in part on the comparison of the first and the second EL test data to the reference model of the reference device.Type: ApplicationFiled: December 20, 2022Publication date: June 22, 2023Inventors: Russell GILABERT, Thomas KENT, Katie T.

Publication number: 20220392016Abstract: In an imaging method, a focal point of a focused optical beam is sequentially mechanically positioned at coarse locations in or on an integrated circuit (IC) wafer or chip. At each coarse location, a two-dimensional (2D) image or mapping tile is acquired by steering the focal point to fine locations on or in the IC wafer or chip using electronic beam steering and, with the focal point positioned at each fine location, acquiring an output signal produced in response to an electrical charge that is optically injected into the IC wafer or chip at the fine location by the focused optical beam. The 2D image or mapping tiles are combined, including stitching together overlapping 2D image or mapping tiles, to generate an image or mapping of the IC wafer or chip. The electronic beam steering may be performed using a galvo mirror. The set of coarse locations may span a three-dimensional (3D) volume.Type: ApplicationFiled: June 2, 2022Publication date: December 8, 2022Inventors: Thomas F. Kent, Jeffrey A. Simon

Publication number: 20130048883Abstract: A treatment safety device is operable by a computer-based treatment safety module to prevent, by at least one of an operational interlock and a warning indicator, a medical treatment unless the treatment safety module determines that predetermined treatment verification criteria are met. The treatment safety device can tie into an existing operational interlock, such as an electrical door interlock. In a radiation oncology application, the treatment safety module verification criteria can include a satisfactory correspondence between elements of a pending treatment and an intended treatment.Type: ApplicationFiled: August 31, 2012Publication date: February 28, 2013Applicant: SUN NUCLEAR CORPORATIONInventors: William E.

Publication number: 20090271270Abstract: Tools for improving interactions between promoters and consumers of products. These tools can enable promoters of products to employ more effective promotional programs, and consumers to receive promotional information about products of interest, while avoiding the excessive overload of information about promotions that are not of interest. Some such tools can enhance consumer satisfaction with—and, correspondingly, consumer participation in—promotional programs by allowing consumers to tailor the discount programs to their preferences, by analyzing consumer behavior and tailoring promotions accordingly, and/or by providing cross promotions of complementary products. Some of the tools can provide substantial savings, in both costs and natural resources, as well as provide a more satisfying experience for consumers, by substantially reducing, or even eliminating, excessive use of paper for promotional programs and transaction receipts.Type: ApplicationFiled: April 24, 2009Publication date: October 29, 2009Applicant: IGCSystems, Inc.Inventors: Manoj Regmi, Jeffrey A.
