Abstract: A power converter incorporating a synchronous rectifier implements adaptive gate voltage regulation for fast turn-off of the synchronous rectifier. In some embodiments, the adaptive gate voltage regulation circuit detects a voltage indicative of a drain current of the synchronous rectifier in each SR conduction cycle and monitors a slope of the detected voltage indicative of a rate of decrease of the drain current of the synchronous rectifier. The adaptive gate voltage regulation circuit further selects a gate discharge current as a function of the slope of the detected voltage to apply to the gate terminal of the synchronous rectifier.

Abstract: Approaches are described for defect detection and analysis in semiconductor substrate (e.g., wafer/reticle) inspection using neural networks and computational models. Disclosed approaches can process images of a semiconductor substrate to identify expected features, such as alignment marks, interconnects, or functional geometries, which represent the intended characteristics of the patterned wafer/reticle's design. These expected features may be provided in various forms, including text-based prompts, CAD-derived reference images, or other design-related data. Such analysis can involve comparing input images with these benchmarks to detect deviations, such as missing features, misalignments, overlapping patterns, or geometric inconsistencies. An example system can allow for analysis of individual images, sub-regions, or multiple images captured across different fabrication stages. Real-time data streams from manufacturing equipment may also be processed for continuous monitoring.
