Abstract:
Various embodiments of packaged chips and ways of fabricating them are disclosed herein. One such packaged chip disclosed herein includes a chip having a front face, a rear face opposite the front face, and a device at one of the front and rear faces, the device being operable as a transducer of at least one of acoustic energy and electromagnetic energy, and the chip including a plurality of bond pads exposed at one of the front and rear faces. The packaged chip includes a package element having a dielectric element and a metal layer disposed on the dielectric element, the package element having an inner surface facing the chip and an outer surface facing away from the chip. The metal layer includes a plurality of contacts exposed at at least one of the inner and outer surfaces, the contacts conductively connected to the bond pads. The metal layer further includes a first opening for passage of the at least one of acoustic energy and electromagnetic energy in a direction of at least one of to said device and from said device.
