The trend to integrate more and more electronic functions in a car, such as window and seat control, fuel injection, air-conditioning etc. requires increasing power handling capabilities, which will force the use of 42V battery operation.
So-called smart power technologies are being developed, able to handle voltages up to 80V on-chip. It is obvious that reliability is one of the major bottlenecks for these technologies. Research at IMO-IMOMEC focuses on hot carrier and high voltage degradation problems in smart power devices. Also, dedicated test methodologies are being developed including DC, AC and combined AC/DC stressing.
