Title: Innovations of Gary R. Gilliam in Defect Testing Circuits
Introduction
Gary R. Gilliam, based in Boise, ID, is a prolific inventor with a remarkable portfolio of 21 patents. His work primarily focuses on advancements in on-chip circuit designs, particularly those used for defect testing in semiconductor technology. His innovative contributions have significantly improved the reliability and performance of electronic devices.
Latest Patents
One of Gary's latest innovations is the patent for an "On-chip Substrate Regulator Test Mode." This on-chip circuit is designed for defect testing, featuring the ability to maintain a substrate voltage at levels that can be more positive or negative than the typical negative operating voltage. The engineering behind this invention involves a chain of MOSFETs configured to function as resistive elements or diodes. Each element in the chain can drop a portion of the supply voltage, leading to an effective substrate voltage that corresponds to the overall supply voltage minus the drops across the diode chain.
A significant advantage provided by this technology is the charge pump that sustains the substrate voltage level set by the chain. It allows for thorough chip testing under various voltage conditions, facilitating the detection of devices that may fail only at cold temperatures or other margin failures resulting from ion contamination.
