Abstract
An ESD protection device for bidirectional diode string triggering SCR structure belongs to the field of electro-static discharge of an integrated circuit. A deep N well is arranged on a P substrate, and a first P well, a first N well, a second P well and a second N well are successively arranged from left to right on a surface region of the deep N well. In a second N well region, a mask preparing plate is used to insert the P wells at intervals. The circumference of each P well is isolated by the N well. Each P well is respectively provided with a pair of P+ implantation region and N+ implantation region. The metal wire is connected with the implantation region, and a positive electrode and a negative electrode are led out from the metal wire for forward conduction and reverse conduction.
