Latest Patents

Wang's latest patents include a dual-directional electrostatic discharge protection method. This invention features a two-terminal ESD protection structure formed by an alternating arrangement of adjacent p-n-p-n-p semiconductor regions. It provides protection against both positive and negative ESD pulses. When an ESD pulse appears across the two terminals, one of the inherent n-p-n-p thyristors is triggered into a snap-back mode, forming a low impedance path to discharge the ESD current. Some embodiments of this structure have enhanced current handling capability and are formed by combining several standard cells, including corner, center, and edge cells. Another notable patent is the dual-directional electrostatic discharge protection device, which also consists of a two-terminal ESD protection structure formed by five adjacent semiconductor regions of alternating conductivity type. This device operates by triggering one of its two inherent thyristors into a snap-back mode, providing a low impedance path for discharging ESD current.
