Latest Patents

Chen’s listed patents address two approaches to ESD protection in semiconductor devices.

“Electrostatic Discharge Protection for Semiconductor Input Devices” describes a circuit that protects an integrated circuit from ESD while supporting input latch-up immunity during normal operation. The design connects a Shockley diode to an input bond pad and the MOSFET transistor being protected. A trigger transistor helps activate the diode at a lower voltage during an ESD event, directing the resulting charge carriers toward the protection structure.

“Electrostatic Discharge Protection for Semiconductor Devices” describes conductor ballast resistor strips placed in series with a transistor. The strips use material with a positive temperature coefficient to counter the negative temperature coefficient of the semiconductor. The design also uses parallel conductor strips and multiple sub-transistors in separate moats to distribute current and reduce the risk of damaging current concentrations.

Career Highlights

Chen’s listed inventions focus on improving the reliability of semiconductor devices under electrical stress. One patent emphasizes triggering a protective diode during an ESD event, while the other addresses current distribution and temperature-related effects in transistor protection. Both reflect practical circuit and device-level approaches to reducing ESD damage.
