Latest Patents

Cai Jun's latest patents include advancements in dummy layer diode structures for electrostatic discharge (ESD) protection. These structures feature a controllable dummy layer that provides a low controllable trigger voltage, serving as a first triggered device in ESD protection networks. The controllable dummy layer diode is designed as a butting diode with a dummy polysilicon layer above the butting region, which functions as an STI block to eliminate the STI between the n+ and p+ regions of the diode. This innovative design allows for adjustments in the reverse-biased voltage of the diode by modifying the channel length under the gate and the gate voltage.

Another significant patent involves a diode-like plasma induced damage protection (PID) device structure. This novel design includes an N-well, three associated N+ regions, and a P+ region formed on a P substrate. The diode-like PID protection device is structured as a butting diode with a polysilicon gate above the butting region. The gate connects to a metal antenna element and a zener-like trigger element, allowing the antenna to capture a portion of the plasma charge to provide a gate voltage. This design minimizes device leakage during normal IC operation by discharging any charge on the poly gate through the N-well resistor.
