Abstract

A high-voltage semiconductor device includes a MOS device and a resistor device. The MOS device has a source, a drain, a drain insulation region adjacent to the drain, and a gate adjacent to the source. The resistor device is formed on the drain insulation region and is electrically connected to the drain. The resistor device has a plurality of resistor sections connected in series, and each of the plurality of resistor sections has a curved shape.
