  • Publication number: 20080198519
    Abstract: An electrostatic discharge protection element is disclosed for protecting an internal circuit from electrostatic current. The electrostatic discharge protection element forms an embedded LVTSCR by adding a prescribed impurity region within an N-well region having a P-type diode formed therein. A P-well region having a GGNMOS transistor is also formed in the electrostatic discharge protection element. The embedded LVTSCR improves area efficiency, reduces a resistance, and lowers an operational voltage by reducing the distance between the P-type diode and the LVTSCR to allow high-speed operatation.
