Innovation in power semiconductor industry: past and future

Power microelectronics plays an important role in many of the consumer and industrial applications today. With increase in demand for energy savings and efficient systems, the requirements for rapid advancement in MOS controlled power semiconductor device concepts and technologies are becoming more crucial than ever before. This puts a considerable pressure on industries to be innovative and competitive at the device, technology, manufacturing, and marketing levels. Today manufacturing companies are faced with intensifying competition and a turbulent economic environment. To some extent technology is seen as a means by which firms can strive to adapt to the requirements of this difficult and uncertain environment. On the other hand, rapid rates of technological change and associated shorter product cycles are themselves part of the difficulty, as is the increased blurring of long-established industrial boundaries (Kodama\´s, 1985) process of "technological fusion". The growing complexity and increased pace of industrial technological change especially in power microelectronics are forcing firms to forge new alliances and to seek greater flexibility and efficiency in responding to market changes. The aim of this paper is to explore these aspects.
