Abstract:
A semiconductor die includes a discrete semiconductor device and at least one diode. The temperature of the discrete semiconductor device is determined by measuring a first forward voltage drop of the at least one diode under a first test condition, measuring a second forward voltage drop of the at least one diode under a second test condition and estimating the temperature of the discrete semiconductor device based on the difference between the first and second forward voltage drop measurements.

Abstract:
A power semiconductor device having a power semiconductor transistor configuration includes: a semiconductor body having a front side coupled to a first load terminal structure, a backside coupled to a second load terminal structure, and a lateral chip edge; an active region for conducting a load current in a conducting state; and an edge termination region separating the active region and lateral chip edge. At the front-side, the edge termination region includes a protection region devoid of any metallic structure, unless the metallic structure is electrically shielded from below by a polysilicon layer that extends further towards the lateral chip edge than the metallic structure by a lateral distance of at least 20 μm. In a blocking state, the protection region accommodates a voltage change of at least 90% of a blocking voltage inside the semiconductor body in a lateral direction from the active region towards the lateral chip edge.
Abstract:
A semiconductor die includes a single power transistor or power diode, a temperature sense diode formed close enough to the single power transistor or power diode to measure an accurate temperature. The temperature sense diode comprises first and second diodes or strings of diodes. A separate integrated circuit is operable to measure first and second voltage drops of both the first and second diodes or strings of diodes using same magnitude currents, and estimate the temperature of the single power transistor or power diode based on the difference between the first and second forward voltage drop measurements. An overall pn junction area of the first diode or string of first diodes is different from an overall pn junction area of the second diode or string of second diodes.
Abstract:
A method of manufacturing a reduced free-charge carrier lifetime semiconductor structure includes forming a plurality of transistor gate structures in trenches arranged in a semiconductor substrate, forming a body region between adjacent ones of the transistor gate structures and forming an end-of-range irradiation region between adjacent ones of the transistor gate structures, the end-of-range irradiation region having a plurality of vacancies.
