Silicon-controlled rectifiers (SCRs) are frequently used to, build on-chip electrostatic discharge (ESD), protection 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. It is demonstrated that HHLVTSCR can exhibit various characteristics useful for ESD solutions. An example is also included to illustrate how HHVLTSCRs can be used to provide ESD protection to a practical application.
