  • Patent number: 11894339
    Abstract: A method of manufacturing a sensor device includes obtaining a semiconductor die structure comprising a transmitter and a receiver. Then, a first sacrificial stud is affixed to the transmitter and a second sacrificial stud is affixed to the receiver. The semiconductor die is affixed to a lead frame, and pads on the semiconductor die structure are wirebonded to the lead frame. The lead frame, the semiconductor die structure, and the wirebonds are encapsulated in a molding compound, while the tops of the first and second sacrificial studs are left exposed. The first and second sacrificial studs prevent the molding compound from encapsulating the transmitter and the receiver, and are removed to expose the transmitter in a first cavity and the receiver in a second cavity. In some examples, the semiconductor die structure includes a first semiconductor die comprising the transmitter and a second semiconductor die comprising the receiver.
