    Abstract: Embodiments of the invention include device packages and methods of forming such packages. In an embodiment, the method of forming a device package may comprise forming a reinforcement layer over a substrate. One or more openings may be formed through the reinforcement layer. In an embodiment, a device die may be placed into one of the openings. The device die may be bonded to the substrate by reflowing one or more solder bumps positioned between the device die and the substrate. Embodiments of the invention may include a molded reinforcement layer. Alternative embodiments include a reinforcement layer that is adhered to the surface of the substrate with an adhesive layer.

    Abstract: An architecture for v-groove fiber attach for a photonic integrated circuit (PIC). The architecture is characterized by a PIC with a thickness of less than 100 microns. A carrier layer is attached to the non-active surface of the PIC and v-grooves are etched into the active surface of the PIC wafer. The carrier layer functions as an etch stop during the etching of the v-grooves, thereby becoming a floor for the v-grooves and enabling the v-grooves to extend to a depth equal to the thickness of the PIC. The carrier layer can be a glass layer. The carrier layer can also be an electronic integrated circuit (EIC).
