Electrostatic discharge (ESD) is a process in which a finite amount of charge is transferred from one object (i.e., human body) to the other (i.e., microchip). This process can result in a very high current passing through the object within a very short period of time. To prevent ESD-induced damages to integrated circuits, it is imperative to develop and implement ESD protection structures. An effective...
A new electrostatic discharge (ESD) protection structure of high-voltage p-type silicon-controlled rectifier (HVPSCR) that is embedded into a high-voltage p-channel MOS (HVPMOS) device is proposed to greatly improve the ESD robustness of the vacuum-fluorescent-display (VFD) driver IC for automotive electronics applications. By only adding the additional n+ diffusion into the drain region of HVPMOS,...
SPICE type simulation using compact models is a very useful tool for predicting circuit performance under ESD stress conditions. However device models valid in the ESD current/voltage operating region are not widely available. This paper starts with a brief description of compact modeling for ESD devices working in snapback mode. A practical macro modeling approach for modeling snapback of MOS and...
