Latest Patents

One of Yongjun Zheng's latest patents is titled "Estimating Icc Current Temperature Scaling Factor of an Integrated Circuit." This invention reduces the resources needed to estimate the Icc Current Temperature Scaling Factor (ITSF) of a device. It provides a method and apparatus to estimate ITSF from the device speed and performance characteristics, which can be measured at room temperature. The method involves determining a level of propagation delay of a portion of the integrated circuit and estimating the Icc current temperature scaling factor based on the correlation between the propagation delay and a modeled ITSF.

Another notable patent is the "Method of Metal Pattern Inspection Verification." This method evaluates an inline inspection recipe by comparing the capture rate of metal pattern defects in bounding boxes arising from failed electrical test vectors to the capture rate after the bounding box is shifted. A difference between the first and second capture rates indicates whether the inline inspection recipe is valid for capturing killer defects or if it needs adjustment. This method is particularly useful for evaluating patterned metal layers in field-programmable gate arrays (FPGAs).
