Abstract

A high-voltage integrated circuit includes a low-voltage circuit region having a plurality of semiconductor devices, which operate with respect to a ground voltage, a high-voltage circuit region having a plurality of semiconductor devices, which operate with respect to a voltage that varies from the ground voltage to a high voltage, a junction termination and a first isolation region electrically isolating the low-voltage circuit region from the high-voltage circuit region, a high-voltage resistant diode formed between the low-voltage circuit region and the high-voltage circuit region, and a second isolation region surrounding the high-voltage resistant diode and electrically isolating the high-voltage resistant diode from the low-voltage circuit region and the high-voltage circuit region.
