Semiconductors in high temperature applications - a future trend in automotive industry

Semiconductors for high temperature become increasingly important for automotive applications. Typical junction temperatures of 150°C (microcontrollers)/200°C (power devices) are requested. To fulfil failure rates of <lppm in automotive applications a lot of investigations result in the following consequences: new design libraries, test concepts, technology and product qualification strategies. In the paper the effort for semiconductor supplier to be able to provide devices for high temperature applications will be presented. Investigations to assure safe high temperature device operation advanced by a European funding project will be introduced. A qualification concept proposal regarding AEC-Q100 will be discussed.
