    摘要: Disclosed is an across-chip temperature sensing circuit and an associated method that can be used to profile the across-chip temperature gradient. The embodiments incorporate a plurality of phase change elements distributed approximately evenly across the semiconductor chip. These phase change elements are programmed to have essentially the same amorphous resistance. Temperature-dependent behavior exhibited by each of the phase change elements individually is compared to a reference (e.g., generated by a discrete reference phase change element, generated by another one of the phase change elements, or generated by an external reference) in order to profile the temperature gradient across the semiconductor chip. Once profiled, this temperature gradient can be used to redesign and/or relocate functional cores, to set stress limits for qualification of functional cores and/or to adjust operating specifications of functional cores.

    摘要: A method of reliability evaluation and system fail warning using on chip parametric monitors. The method includes determining impact of parametric variation on reliability by identifying key parametric questions to be answered by stress, identifying parametric macros for each parameter, and identifying layout sensitive areas of evaluation. The process can also include a set of parametric macros in one of a test site or a product to be stressed, testing the set of parametric macros prior to start of stress and at each stress read out, and setting life time parameter profile for technology.

    摘要: A hardware description language (HDL) design structure for performing device-specific testing and acquiring parametric data on integrated circuits, such that each chip can be tested individually without excessive test time requirements, additional silicon, or special test equipment. The HDL design structure includes a functional representation of at least one device test structure integrated into an IC design which tests a set of dummy devices that are identical or nearly identical to a selected set of devices contained in the IC. The test structures are integrated from a device under test (DUT) library according to customer requirements and design requirements. The functional representations of selected test structures are further prioritized and assigned to design elements within the design in order of priority. Placement algorithms use design, layout, and manufacturing requirements to place the selected functional representations of test structures into the final layout of the design.

    摘要: A method for predicting and controlling leakage wherein an IDDQ prediction macro is placed in a plurality of design topographies and data is collected using the IDDQ prediction macro. The IDDQ prediction macro is configured to measure subthreshold leakage and gate leakage for at least one device type in a semiconductor test site and in scribe lines using the IDDQ prediction macro and establish a leakage model. The method correlates the semiconductor test site measurements and the scribe line measurements to establish scribe line control limits, predicts product leakage; and sets subthreshold leakage limits and gate leakage limits for each product using the leakage model.

    摘要: A block of phase change material located in a semiconductor chip is reset to an amorphous state. The block of phase change material may be connected to an internal resistance measurement circuit that can transmit the measured resistance data to input/output pads either in an analog output format or in a digital output format. Depending on the ambient temperature, the resistance of the block of phase change material changes. By measuring a fractional resistance change compared to the resistance of the phase change material at a calibration temperature, the temperature of the region around the phase change material can be accurately measured. A logic decoder and an input/output circuit may be employed between the internal resistance measurement circuit and the input/output pads. A plurality of temperature sensing circuits containing phase change material blocks may be employed in the semiconductor chip to enable an accurate temperature profiling during chip operation.
