Monolithic integration of 5 V CMOS and high-voltage devices

摘要

A fully CMOS-compatible HVIC technology has been developed that features 5 V high-performance digital CMOS with high-voltage devices of more than 400 V. This technology uses only one or two masks in addition to standard p-well CMOS technology. Design optimization has been achieved to meet the needs of both CMOS and high-voltage devices. A large number of different devices are available in this technology, including bipolar transistors, lateral MOS gate power devices, and high-voltage p-channel power devices.
