Description

Advances in power transistor design and process technology development have allowed the cost efficiencies of monolithic power integrated circuits to be applied in the power control areas. Power integrated circuits (PICs), which combine power transistors and low voltage control circuitry on a single IC chips, were initially applied in the area of telecommunications, high-voltage displays, power supplies, motor controls, and automotive systems, and are likely to spread to the areas of consumer products such as appliances, air conditioners, lighting ballasts as well as programming controls and robotics. Apart from cost efficiency, the PIC approach also provides the advantage of higher functionality, greater reliability, and reduced size and weight, which make possible many novel applications in the power control area.

The objective of this project is to devise high-performance integrable power transistor for the various applications. The transistors should have the characteristics of low on-state resistance, high switching speed, high breakdown voltage, and also compatibility to the VLSI fabrication technology. Research involved in this project include power transistor design, modelling, implementation, characterisation, and optimisation; technology development, process modelling, and process integration.
