Abstract: Aspects of the embodiments are directed to systems and devices that include a piezo-electric element comprising a top-side electrode and a bottom-side electrode; a metal contact pad electrically connected to the bottom-side electrode; an electrode electrically connected to the top-side electrode; and an encasement encasing the piezo-electric element. The piezo-electric element can be prepared to include steps and metallization for use in one or more types of packaging.

Abstract: A semiconductor package may include an electrically conductive leadframe having a aperture extending from an upper surface of the leadframe to the lower surface of the leadframe. A wirebond die may be attached or affixed to the upper surface of the leadframe in a location that at least partially obstructs the aperture. A flip-chip die may be disposed proximate the bottom surface of the leadframe at least partially in the aperture. The flip-chip die may be physically coupled to the wirebond die, the leadframe, or both. A mold compound that exposes the lands on the leadframe and the solder bumps or balls on the flip-chip die may at least partially encapsulate the semiconductor package.

Abstract: An optical touchscreen assembly may employ a photonic chip packaged with a chip surface at an angle inclined between horizontal and vertical orientations. An inclined paddle sawn flat no-leads (IPSFN) package may be affixed to a cover glass surface along a perimeter of a display. IPSFN packages may incorporate a photo-emitter chip and a photo-detector chip that may be inclined for a desired angle of incidence relative to the cover glass. A CMOS integrated optical transceiver package may include inclined photonic chips and a non-inclined CMOS chip having at least one of a photo-emitter driver, or a photo-detector TIA and/or ADC. A chip package lead frame may include cantilevered paddle tabs amenable to controlled deflection during package assembly. An inclined packaging assembly method may include attaching a chip to a lead frame paddle and form pressing the lead frame to incline the chip to a desired angle before encapsulation.
