Latest Patents

Travis is credited with a patent titled "Method, system and apparatus to detect defects in semiconductor devices." This invention introduces a novel method and system designed to locate and identify voids in films integral to both critical dimension (CD) structures and non-critical dimension structures within semiconductor devices. The technology employs one or more test structures, referred to as resolution devices, which are created on a semiconductor wafer. Utilizing a scanning electron microscope (SEM) configured in voltage contrast mode, the system captures a digital representation of the test structure. The analysis mechanism automates the location, identification, and classification of voids found, proving to be more sensitive to electrical marginalities caused by these voids compared to traditional wafer electrical testing methods. This innovative approach is particularly valuable for inline monitoring during manufacturing processes, enabling efficient automation of defect identification and categorization.
