An semiconductor device is disclosed. The device includes a semiconductor body, a layer of insulating material disposed over the semiconductor body, and a region of gate electrode material disposed over the layer of insulating material. Also included are a source region adjacent to gate region and a drain region adjacent to the gate region. A gate connection is disposed over the semiconductor body, wherein the gate connection includes a region of gate electrode material electrically coupling a contact region to the gate electrode. An insulating region is disposed on the semiconductor body beneath the gate connection.

Method and layout of semiconductor device with reduced parasitics

A protective device in a semiconductor may comprise a substrate of a first conductivity type, an epitaxial layer formed on top of the substrate, a body area formed within the epitaxial layer of a second conductivity type extending from a top surface into the epitaxial layer, a first area of the first conductivity type extending from the top surface into the body area, an isolation area surrounding the first area, a ring area of the first conductivity type surrounding the isolation area, and a coupling structure for connecting the ring area with the substrate.

Integrated circuit ESD protection
