Title: Innovations by Douglas C Heaberlin
Introduction
Douglas C Heaberlin is a notable inventor based in Underhill, Vermont, known for his contributions to integrated circuit technology. He has been awarded a total of 6 patents throughout his career, showcasing his expertise in diagnosing defects in integrated circuits.
Latest Patents
One of Heaberlin's latest patents focuses on the exhaustive diagnosis of bridging defects in integrated circuits. This method involves measuring the quiescent power supply current of the integrated circuit under multiple test vectors. By obtaining the logic states of the nodes on the integrated circuit, Heaberlin partitions these nodes into sets based on their logic states under low-current test vectors. This innovative approach allows for efficient evaluation under the Ibridge fault model, saving system resources while achieving comprehensive diagnosis.
Another significant patent addresses the improvement of the signal-to-noise ratio in Idefect tests. In this method, an integrated circuit is divided into several areas, each equipped with terminals. By activating an Idefect to generate current within the circuit, Heaberlin measures the Idefect current at the terminals. This data is used to create an Icurrent map, which helps in determining the presence and location of defects, ultimately leading to their isolation.
