Abstract
For maintaining the regular operating current in an inner circuit under electrostatic discharge (ESD) event, an ESD protection device is provided to control an ESD path switch in the turned-on condition by employing a MOS device and a latch-detected turned-on circuit. The MOS device has a self-aligned silicidation (Salicide) therein. The ESD protection device is used to stabilize operation efficiency and reduce the area of an ESD protection device without a silicide block disposed therein for enhancing the ESD protection capability.
