Latest Patents

Wong's latest invention, the Low Capacitance ESD Protection Device, is designed to protect MOS (Metal-Oxide-Semiconductor) circuits from damaging ESD voltages. The device features an N-well of very short length arranged in a P-well or P-substrate, diffused with P+ diffusion to form a diode. This design incorporates a parasitic pnp bipolar transistor shared by two parasitic SCRs (Silicon-Controlled Rectifiers). Notably, the junction capacitance of the N-well is incredibly low, approximately 0.03 pF, which enhances the device's efficiency. Flanking the N-well are NMOS transistors, with their drains coupled to a chip pad that connects to the MOS circuits needing protection. The innovation allows the ESD pulse to drive the NMOS transistors into conduction and safely channel the discharge current, ensuring the integrity of sensitive chip components.
