    摘要: A monitor for detecting pass gate leakage in a silicon on insulator device and a method for using the same is described herein. A pulse generator supplies a signal to a set of buffers connected in parallel, which pass on a signal to the source side of a series of NFETs. The plurality of NFETs are ordered by increasing channel widths. The NFETs have grounded gates, and therefore will not pass current due to field effects. Each NFET is connected to a latch, and the latches are originally set to the same state. When the signal supplied to the NFET drops from high to low, pass gate leakage will occur through the channel of each NFET. If pass gate leakage through any given NFET is sufficient, the latch will change states. The latch output signal is sent to a shift register, which can be made to output information. By incorporating the monitor on the chip, pass gate leakage tolerances and specifications can be established in-line during manufacture.

    摘要: A method and system for predicting gate reliability. The method comprises the steps of stressing a gate dielectric test site to obtain gate dielectric test site data and using the test site data to predict gate reliability. Preferably, the test structure and the product structure are integrated in such a manner that a test site occupies some of the product area and the product itself occupies the remainder of the product area. A preferred methodology, more specifically, is as follows: (1) Test structures at start both in parallel stress mode and in ring oscillator or “product” mode; (2) Analyze the breakdown data as per the present state of the art for each of the areas based on the parallel stress mode; (3) Combine the above breakdown distributions using the area scaling to improve the confidence bounds of the Weibull slope of the cumulative distribution function; (4) Test the ring oscillators in the product mode to determine how many of the stress fails are also product fails as defined by an operational degradation; (5) Subdivide the failures to determine the relationship between the first fail, and the second fail, and the nth fail; (6) Investigate which stress fail, if not the first stress fail, is more likely to cause a product fail as defined by operational degradation; and (7) Based on the subdivision in step 5 and the results in step 6, make projection based on that fail which is most likely to cause fail. The methodology as outlined above bridges between dielectric stress fails and product degradation both in the case of each stress fail causing a product degradation, as well as in the case where more than one stress fail occurs before any product degradation occurs. And this relationship can be quantified.

    摘要: An SOI chip having an isolation barrier. The SOI chip includes a substrate, an oxide layer deposited on the substrate, and a silicon layer deposited on the oxide layer. A gate is deposited above the silicon layer. A first metal contact is deposited above the gate to form an electrical contact with the gate. Second and third metal contacts are deposited to form electrical contacts with the silicon layer. The isolation barrier extends through the silicon layer and the oxide layer, and partially into the substrate, to block impurities in the oxide layer outside the isolation barrier from diffusing into the oxide layer inside the isolation barrier. The isolation barrier surrounds the gate, the first metal contact, the second metal contact, and the third metal contact—which define an active chip area inside the isolation barrier. A method of manufacturing the SOI chip is also disclosed.

    摘要: Disclosed are embodiments of a semiconductor chip structure and a method that incorporate a localized, on-chip, repair scheme for devices that exhibit performance degradation as a result of negative bias temperature instability (NBTI). The repair scheme utilizes a heating element above each device. The heating element is configured so that it can receive transmission line pulses and, thereby generate enough heat to raise the adjacent device to a temperature sufficient to allow for performance recovery. Specifically, high temperatures (e.g., between approximately 300-400° C. or greater) in the absence of bias can accelerate the recovery process to a matter of seconds as opposed to days or months. The heating element can be activated, for example, on demand, according to a pre-set service schedule, and/or in response to feedback from a device performance monitor.
