Abstract
The high voltage integrated circuit is disclosed. The high voltage integrated circuit comprises a low voltage control circuit, a floating circuit, a P substrate, a deep N well disposed in the substrate and a plurality of P wells disposed in the P substrate. The P wells and deep N well serve as the isolation structures. The low voltage control circuit is located outside the deep N well and the floating circuit is located inside the deep N well. The deep N well forms a high voltage junction barrier for isolating the control circuit from the floating circuit.
