Abstract
A stacked die sensor package includes a die paddle and lead fingers that surround the die paddle. The lead fingers have proximal ends near the die paddle and distal ends spaced from the die paddle. A first semiconductor die is mounted to one side of the die paddle and electrically connected to the lead fingers with first bond wires. A sensor die is mounted to the other side of the die paddle and electrically connected to the lead fingers with sensor bond wires. An encapsulation material covers the first die and the first bond wires, while a gel material and a lid cover the sensor die and the sensor bond wires. The package may also have a second semiconductor die attached on an active surface of the first die and electrically connected one or both of the lead fingers or first die bonding pads with second bond wires.
