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 and a second semiconductor region, and the second semiconductor controlled rectifier includes the first semiconductor region and the second semiconductor region. 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.
