Robust Electrostatic Discharge (Esd) Protection For Microchips

Silicon controlled rectifiers (SCRs) are frequently used to build on-chip electrostatic discharge (ESD) structures, but SCRs are not sufficiently robust to meet a wide range of ESD requirements in various integrated circuits. In this paper, a novel and robust SCR-based device called the HHLVTSCR is presented. Examples are also included to illustrate how HHVLTSCRs can be used to provide ESD protection in two different IC applications
