Title: Van-Hung Pham: Innovator in Semiconductor Technology
Introduction
Van-Hung Pham is a notable inventor based in Milpitas, California. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on methods for enhancing the reliability and performance of semiconductor devices.
Latest Patents
One of his latest patents is titled "Method and system for non-destructive determination of dielectric breakdown voltage in a semiconductor wafer." This innovative method involves injecting a test current in increasing ramp steps into the dielectric layer of a semiconductor substrate. The process includes measuring the test voltage across the dielectric layer at each step and detecting a dropped test voltage in response to the increasing current. The breakdown voltage is determined to be substantially equal to the dropped test voltage.
Another significant patent is "Dielectric breakdown lifetime enhancement using alternating current (AC) capacitance." This patent describes a method for determining the time-to-breakdown for a dielectric layer in a semiconductor device based on sudden changes in capacitance. An alternating voltage, greater than the device's operating voltage, is applied, and capacitance is measured until a sudden change occurs, indicating a breakdown in the dielectric layer.
