Latest Patents

One of Wipawan's latest patents is titled "Trim zener using double poly process." This invention involves a zener zap diode device and a system for creating such a device using a double poly process. In this process, p+ and n+ regions are formed in a tub through p-doped and n-doped polysilicon regions, establishing a p-n junction. The invention also describes how cobalt or other refractory metals can react with silicon to form a silicide on the p-doped polysilicon region. By reverse biasing the p-n junction and applying a sufficiently high zap current, the silicide can migrate across the junction, forming a silicide bridge that selectively shorts out the p-n junction.

Another notable patent is "Elimination of walkout in high voltage trench isolated devices." This invention addresses the issue of walkout in high voltage trench isolated semiconductor devices. By applying a voltage bias signal directly to the epitaxial silicon surrounding the device, the initial breakdown voltage is elevated, effectively eliminating walkout. The application of a positive voltage bias signal ensures that no walkout occurs during normal operation.
