Structures for an electrostatic discharge device including a silicon-controlled rectifier and methods of forming a structure for an electrostatic discharge device that includes a silicon-controlled rectifier. The structure includes a first well in a semiconductor substrate, a second well and a third well in the first well, and a fourth well in the first well. The first well has a first conductivity type, and the second well and the third well have the first conductivity type. The fourth well positioned in a lateral direction between the second well and the third well, and the fourth well has a second conductivity type opposite to the first conductivity type. The second well, the third well, and the fourth well are positioned in a vertical direction between the first well and a top surface of the semiconductor substrate.

The present disclosure generally to semiconductor devices, and more particularly to semiconductor devices having high-voltage transistors integrated on a semiconductor-on-insulator substrate and methods of forming the same. The present disclosure provides a semiconductor device including a bulk substrate, a semiconductor layer above the bulk substrate, an insulating layer between the semiconductor layer and the bulk substrate, a source region and a drain region on the bulk substrate, a gate dielectric between the source region and the drain region, the gate dielectric having a first portion on the bulk substrate and a second portion on the semiconductor layer, and a gate electrode above the gate dielectric.

Embodiments of the disclosure provide an integrated circuit device and related methods. The disclosure may provide a transistor device, including: a gate structure; a drain extension region extending laterally from partially under the gate structure to a drain region; and a gate spacer located over the drain extension region. A silicide-blocking layer is over and in contact with the gate spacer. The silicide-blocking layer has a first end over the gate structure and a second, opposing end over the drain extension region. The structure also provides a conductive field plate, including a conductive layer over and in contact with the silicide-blocking layer. A field plate contact is formed on the conductive field plate.
