Active Electrostatic Discharge (ESD) Device for On-Chip ESD Protection in Sub-Quarter-Micron Complementary Metal-Oxide Semiconductor (CMOS) Process

A novel electrostatic discharge (ESD) protection device with a threshold voltage of 0V for complementary metal-oxide semiconductor (CMOS) integrated circuits in sub-quarter-micron CMOS technology is proposed. Quite different to the traditional ESD protection devices, such an active ESD device is originally standing in its turn-on state when the IC is zapped under ESD events. Therefore, such an ...

Dummy-Gate Structure to Improve Turn-on Speed of Silicon-Controlled Rectifier (SCR) Device for Effective Electrostatic Discharge (ESD) Protection

Turn-on speed is the main concern for on-chip electrostatic discharge (ESD) protection device, especially in deep submicron complementary metal-oxide semiconductors (CMOS) processes with ultra-thin gate oxide. A novel dummy-gate-blocking silicon-controlled rectifier (SCR) device with substrate-triggered technique is proposed to improve the turn-on speed of SCR device for using in on-chip ESD pr...

A floating gate design for electrostatic discharge protection circuits

In this paper, a circuit design method for electrostatic discharge (ESD) protection is presented. It considers the gate floating state for ESD protection and negatively gate biased for leakage suppression under normal operations. The circuit is achieved by adding a switch device and a negatively biased circuit at the gate of ESD protection devices. Robustness and leakage of ESD protection circu...

Electrostatic Discharge Protection Circuit for High-Speed Mixed-Signal Circuits

ESD, the discharge of electrostatically generated charges into an IC, is one of the most important reliability problems for ultra-scaled devices. This electrostatic charge can generate voltages of up to tens of kilovolts. These very high voltages can generate very high electric fields and currents across semiconductor devices, which may result in dielectric damage or melting of semiconductors a...
