Abstract
The invention provides a low inductance semiconductor package for RF circuits having a flat leadframe with internal leads formed upward to be in very close proximity to the die mount pad. The die mount pad is exposed through the package backside and serves both as a ground plane and as a heat spreader. The external leads are flat and extend beyond the package edge so that good solder connections to a printed wiring board can be made and inspected. The lead tips exposed beyond the package further provide a position for mold clamping and for test probing the device.
