Fujitsu Laboratories Ltd. announced the development of a technology that enables the manufacture of power-supply transistors on nearly any flat surface, including glass, plastic, or copper. High breakdown-voltage was achieved by forming a high breakdown-voltage power-supply transistor on a target substance using zinc-oxide (ZnO) material and protecting the transistor’s channel using a polymer layer. This new technology will enable power-supply circuits to be manufactured on a wide range of flat surfaces, with potential applications including sensors and piezoelectric devices.

A major issue in reducing environmental footprints is reducing the power consumed by electrical power supplies in applications such as IT equipment, household appliances, and automobiles. At the same time, demand to lower the costs of general-purpose power-supply circuits has generated anticipation for the realization of low-cost power-supply transistors which feature high breakdown-voltages.
