Abstract
A chip scale power semiconductor device (16) provides improved heat dissipation. A semiconductor die (19) is mounted in a first region of a substrate (18). The substrate is extended to a second region for disposing terminals (38) to make external connections to the semiconductor device. Conductors (34) formed on the substrate electrically couple the semiconductor die to the terminals. The substrate is extended for a predetermined distance to separate the second region from the first region for isolating the temperature of the semiconductor die from the local temperature at the terminals.
Claims4
A semiconductor package, comprising:
- a flexible substrate having a plurality of conductors routed along the flexible substrate between a mounting region of the flexible substrate and a terminal region of the flexible substrate wherein the mounting region is physically separated a distance of at least 2.0 millimeters from the terminal region to thermally isolate the mounting region and the terminal region;
- and
- a heat generating semiconductor device having a first surface disposed on the mounting region of the flexible substrate, where the heat generating semiconductor device is mountable to a heat dissipating surface for dissipating the heat generated by the semiconductor device.
