Low Voltage Power MOSFETs focuses on the design of low voltage power MOSFETs and the relation between the device structure and the performance of a power MOSFET used as a switch in power management applications. This SpringerBriefs close the gap between detailed engineering reference books and the numerous technical papers on the subject of power MOSFETs. The material presented covers low voltage applications extending from battery operated portable electronics, through point of load converters, internet infrastructure, automotive applications, to personal computers and server computers. The issues treated in this volume are explained qualitatively using schematic illustrations, making the discussion easy to follow for all prospective readers.

The integration of high voltage power transistors with control circuitry to form smart Power Integrated Circuits (PIC) has numerous applications in the areas of industrial and consumer electronics. These smart PICs must rely on the availability of high performance power transistors. In this thesis, a vertical U-shaped gate MOSFET (UMOS) and a lateral Extended Drain MOSFET (EDMOS) with enhanced electrical characteristics are proposed, developed and verified via experimental fabrication. The proposed new process and structure offers superior performance, such as low on-resistance, low gate charge and optimized high breakdown voltage.In the vertical power UMOS, a novel trenched Local Oxidation of Silicon (LOCOS) process has been applied to the vertical gate structure to reduce the gate-to-source overlap capacitance (Cgs). A 40% reduction in Cgs is achieved when compared to conventional UMOS. A specific on-resistance Ron,sp = 60mO˙mm2 is observed, which is 45% better than that of the conventional UMOS. The improvement in the device's Figure-of-Merit (FOM = Ron x Qg) is about 58%.A floating RESURF EDMOS (BV=55V, Ron,sp=36.5mO˙mm 2) with a 400% improvement in the Safe Operating Area (SOA) when compared to the conventional EDMOS structure is also presented. The proposed EDMOS employs both drain and source engineering to enhance SOA, not only via reducing the base resistance of the parasitic bipolar transistor, but also suppressing the base current of the parasitic bipolar transistor under high Vgs and high Vds conditions. A buried deep Nwell allows the device to have better trade-off between breakdown voltage and on-resistance.Finally, in order to achieve low gate charge in the EDMOS, a novel orthogonal gate electrode is proposed to reduce the gate-to-drain overlap capacitance (Cgd). The orthogonal gate has both horizontal and vertical sections for gate control. This device is implemented in a 0.18mum 30V HV-CMOS process. Compared to a conventional EDMOS with the same voltage and size, a 75% C gd reduction is observed. The FOM is improved by 53%.

Download and read online ebook Advanced Power MOSFET Concepts write by B. Jayant Baliga. This book was released on 2010-06-26. Advanced Power MOSFET Concepts available in PDF, EPUB and Kindle. During the last decade many new concepts have been proposed for improving the performance of power MOSFETs. The results of this research are dispersed in the technical literature among journal articles and abstracts of conferences. Consequently, the information is not readily available to researchers and practicing engineers in the power device community. There is no cohesive treatment of the ideas to provide an assessment of the relative merits of the ideas. "Advanced Power MOSFET Concepts" provides an in-depth treatment of the physics of operation of advanced power MOSFETs. Analytical models for explaining the operation of all the advanced power MOSFETs will be developed. The results of numerical simulations will be provided to give additional insight into the device physics and validate the analytical models. The results of two-dimensional simulations will be provided to corroborate the analytical models and give greater insight into the device operation.
