A test structure is disclosed for locating electromigration voids in a semiconductor interconnect structure having an interconnect via interconnecting a lower metallization line with an upper metallization line. In an exemplary embodiment, the test structure includes a via portion the top of the interconnect via at the upper metallization line. In addition, a line portion extends from the via portion, wherein the line portion connects to an external probing surface, in addition to a probing surface on the lower metallization line, thereby allowing the identification of any electromigration voids present in the interconnect via.

摘要:
An array of radiation sensors or detectors is integrated within a three-dimensional semiconductor IC. The sensor array is located relatively close to the device layer of a circuit (e.g., a microprocessor) to be protected from the adverse effects of the ionizing radiation particles. As such, the location where the radiation particles intersect the device layer can be calculated with coarse precision (e.g., to within 10 s of microns).

The present invention provides a micro-electro-mechanical-system (MEMS) temperature sensor that employs a suspended spiral comprising a material with a positive coefficient of thermal expansion. The thermal expansion of the suspended spiral is guided to by a set of guideposts to provide a linear movement of the free end of the suspended spiral, which is converted to an electrical signal by a set of conductive rotor azimuthal fins that are interdigitated with a set of conductive stator azimuthal fins by measuring the amount of capacitive coupling therebetween. Real time temperature may thus be measured through the in-situ measurement of the capacitive coupling. Optionally, the MEMS temperature sensor may have a ratchet and a pawl to enable ex-situ measurement.
