A COMPACT SCR DEVICE AND METHOD FOR INTEGRATED CIRCUITS

摘要

A semiconductor device and method for electrostatic discharge protection. The semiconductor device includes a first semiconductor controlled rectifier and a second semiconductor controlled rectifier. The first semiconductor controlled rectifier includes a first semiconductor region (152) and a second semiconductor region (160), and the second semiconductor controlled rectifier includes the first semiconductor region (152) and the second semiconductor region (160). The first semiconductor region is associated with a first doping type, and the second semiconductor region is associated with a second doping type different from the first doping type. The second semiconductor region is located directly on an insulating layer (140).
