Abstract
A semiconductor device with substrate-triggered ESD protection has a guard ring, a first MOS transistor array, a second MOS transistor array, a substrate-triggered portion, and an N-well. The first MOS transistor array, the second MOS transistor array, the substrate-triggered portion, and the N-well are formed in a region surrounded by the guard ring, and the substrate-triggered portion is located between the first MOS transistor array and the second MOS transistor array. When the ESD event occurs, the N-well is biased for directing a trigger current.
