摘要: A benchmark device and a method for evaluating a semiconductor wafer are provided. The benchmark device includes a first grating coupler, a second grating coupler and a waveguide. The waveguide has a least one bending section and is arranged in communication with the first grating coupler and the second grating coupler. The bending section comprises a first region having a first width and a first height, and a second region having a second width and a second height, wherein the first region is surrounded by the second region, and the second width decreases gradually from a first end of the bending section to a second end of the bending section.

摘要: A process for making and using a semiconductor wafer includes instantiating first and second designs of experiments (DOEs), each comprised of at least two fill cells. The fill cells contain structures configured to obtain in-line data via non-contact electrical measurements (“NCEM”). The first DOE contains fill cells configured to enable non-contact (NC) detection of side-to-side shorts, and the second DOE contains fill cells configured to enable NC detection of chamfer shorts. The process may further include obtaining NC measurements from the first and/or second DOE(s) and using such measurements, at least in part, to selectively perform additional processing, metrology or inspection steps on the wafer, and/or on other wafer(s) currently being manufactured.

摘要: An IC includes logic cells, selected from a standard cell library, and fill cells, configured for compatibility with the standard logic cells. The fill cells contain structures configured to obtain in-line data via non-contact electrical measurements (“NCEM”). The IC includes such NCEM-enabled fill cells configured to enable detection and/or measurement of a variety of open-circuit and short-circuit failure modes, including at least one via-open-related failure mode, one AACNT-short-related failure mode, one GATECNT-short-related failure mode, and one metal-short-related failure mode.

摘要: A test system includes a test socket assembly for capturing low energy electromagnetic emissions from radio frequency (RF) integrated circuits (ICs). The test socket assembly is structured to direct electromagnetic radiation from the device under test (DUT) to a socket port coupled to one end of a waveguide for transmission to a tester. The combination of the materials comprising the socket assembly is selected to more efficiently couple electromagnetic emissions from the DUT into the waveguide. For example, a reflective plane with an adjustable position may be located below the DUT in order to increase coupling of electromagnetic radiation from the DUT into the waveguide.

摘要: Described are various embodiments of methods and systems for tracing circuitry on integrated circuits using focused ion beam based imaging techniques. In one such embodiment, a method is provide for identifying functional componentry associated with a switchable power interface on an integrated circuit, wherein the switchable power interface comprises a source and a drain with a control switch therebetween, said control switch being controllable by a control signal during operation of the integrated circuit. The method comprises connecting, with deposited conductive material, the source and the drain; applying an external voltage bias to a power input of the switchable power interface via one of the source and the drain; exposing the integrated circuit to a focused ion beam; and gathering an image of the integrated circuit during exposure to determine areas of high contrast indicating functional componentry in operative connection with the switchable power interface.
