Description

technical field [0001] The present invention relates to a high-voltage semiconductor device, in particular to a high-voltage semiconductor device that can be integrated with a metal-oxide-semiconductor (MOS) transistor device. Background technique [0002] A transistor device is an element used in a circuit to switch a switch or enhance an electronic signal. In the early development of solid-state electronic circuits, bipolar junction transistors (bipolar junction transistors, BJT) components were the main components. With the increasing demand for high-speed, low-cost, and small-size digital devices, modern integrated circuits are The main force is metal-oxide-semiconductor field transistor (MOSFET) components. [0003] However, the current breakdown voltage of the MOSFET device is less than about 100 volts (volt, V), so it cannot be applied in a high-voltage environment or an ultra-high voltage environment with a voltage as high as 500V to 1200V. Therefore, there is stil...
