Title: Michael Cheng: Innovator in Electrostatic Discharge Protection Technology
Introduction
Michael Cheng is a notable inventor based in Singapore, SG. He has made significant contributions to the field of electrostatic discharge (ESD) protection devices. With a total of 2 patents, Cheng's work focuses on enhancing the reliability and performance of electronic components.
Latest Patents
Cheng's latest patents include an innovative electrostatic discharge protection device featuring complementary dual drain implants. This technology involves the formation of off-chip driver (OCD) NMOS transistors with ESD protection. The design interposes a P-ESD implant between the N+ drain regions of the OCD NMOS transistors and the N-well. This configuration allows the P-ESD to surround a section of the N-well, enhancing the device's performance. The P-ESD implant is dosed less than the N+ source/drain implants but higher than the N-well dose. In another embodiment, N-well doping is utilized alongside P-ESD doping, ensuring that the P-ESD doping counterdopes the N-well beneath the N+ drains while maintaining electrical connection. This innovative approach creates a larger surface area under the junction breakdown region and increases the radius of curvature of the junction. Additionally, the P-ESD implant is covered by N-type material on three sides, which improves the parasitic bipolar transistor characteristics.
