WAFER-LEVEL CAVITY PACKAGE WITH BACKSIDE TERMINATION
A wafer-level cavity package with backside termination is disclosed. In one aspect, a package includes an air cavity that is adjacent to a substrate. Input/output (I/O) vias extend from the circuits in the air cavity through the substrate for connection to external pads for the package. A cap covers the air cavity and does not include metal conductors therethrough. By routing the vias through the substrate instead of the cap, numerous advantages are realized, including better thermal pathing, improved structural integrity of the cap, reductions in die and module stress, tighter frequency variation, enhanced yield, and options for shrinking overall package geometry.

Method and electronic device for monitoring the temperature of power electronics, and motor vehicle
A method and an electronic device monitors the temperature of power electronics having at least one power transistor. In the method, during active operation of the power transistor, the drain-source voltage and the drain current of the transistor are measured and are used to calculate an on-state resistance. An instantaneous junction temperature of the power transistor is determined for monitoring the temperature on the basis of a predefined assignment. The predefined assignment is automatically recalibrated for future operation of the power transistor by automatically measuring in each case a pair of values of the instantaneous on-state resistance and an instantaneous temperature of the power electronics in each case at a plurality of different times outside active operation. These temperatures are measured at a location spatially spaced apart from the junction of the power transistor and are assumed to be junction temperatures prevailing at the respective time. The assignment is then updated according to these pairs of values.
