Abstract:
1. A stacked die sensor package, comprising: a die paddle having a first side and an opposite second side; lead fingers that surround the die paddle, each lead finger having a proximal end near a respective edge of the die paddle and a distal end providing an external electrical connection for the package; a first semiconductor die having an active surface with first die bonding pads and an opposite die mount surface attached to the first side of the die paddle; a sensor die having a sensor active surface with sensor die bonding pads and an opposite sensor surface attached to the second side of the die paddle; sensor bond wires selectively electrically connecting the sensor die bonding pads to the proximal ends of the lead fingers; die bond wires selectively electrically connecting the first die bonding pads to the proximal ends of the lead fingers; an encapsulating material that covers the first semiconductor die and the die bond wires, wherein the encapsulating material has an outer package base surface and an opposite planar surface and the lead fingers distal ends are exposed from the encapsulating material at the outer package base surface for providing the external electrical connections, and the lead fingers proximal ends are exposed from the encapsulating material at the opposite planar surface; and a footed lid mounted to the opposite planar surface of the encapsulating material and covering the sensor die and the sensor bond wires, wherein the footed lid includes a hole in a surface thereof.
