摘要
An alternative CMOS manufacturing process architecture for implementing Power Integrated Circuits that may be used for applications requiring a bridge topology is presented. A RESURF N-LDMOS High-Side compatible power transistor was designed onto the new process using TSuprem4 and Medici TCAD software. Masks were designed using Cadence Virtuoso and the new structure was manufactured at X-Fab UK Ltd. The physical results show good transistor characteristics compatible for high-side applications. The Specific RDSon for the new device is 260m Omega.mm(2) and breakdown voltage for both high-side and low-side operation exceeds 100V.
