Abstract
An integrated circuit structure includes a semiconductor substrate, a first source/drain feature, a second source/drain feature, a gate dielectric layer, a gate electrode, a field plate electrode, and a dielectric layer. The semiconductor substrate has a well region and a drift region therein. The first source/drain feature is in the well region. The second source/drain feature is in the semiconductor substrate. The drift region is between the well region and the second source/drain feature. The gate dielectric layer is over the well region and the drift region. The gate electrode is over the gate dielectric layer and vertically overlapping the well region. The field plate electrode is over the gate dielectric layer and vertically overlapping the drift region. The dielectric layer is between the gate electrode and the field plate electrode. A top surface of the gate electrode is free of the dielectric layer.
