Abstract:
In various embodiments, an electronic module features a first cavity in a first side of a substrate, a fill hole extending from the first cavity, and a second cavity in a second side of the substrate. The second cavity is in fluidic communication with the fill hole, and a die is encapsulated within the second cavity.
Abstract:
A microelectronic unit 12 includes a substrate 20 and an electrically conductive element 40. The substrate 20 can have a CTE less than 10 ppm/°C, a major surface 21 having a recess 30 not extending through the substrate, and a material 50 having a modulus of elasticity less than 10 GPa disposed within the recess. The electrically conductive element 40 can include a joining portion 42 overlying the recess 30 and extending from an anchor portion 41 supported by the substrate 20. The joining portion 42 can be at least partially exposed at the major surface 21 for connection to a component 14 external to the microelectronic unit 12.

Abstract:
Exemplary embodiments provide methods and systems for assembling electronic devices, such as integrated circuit (IC) chips, by selectively and scalably embedding or seating IC elements onto/into a receiving substrate, such as a chip substrate. Specifically, the assembly of IC chips can include forming a pocket in the receiving substrate to accommodate the IC elements therein. Such pockets can be formed in the receiving substrate using laser ablation.
Abstract:
An embedded die package includes a carrier with an electrical device in the cavity of the carrier, a first dielectric layer covering the sides and top of the electrical device except for vias over selected bonding pads of the electrical device, a plurality of metal conductors, each of which is in contact with at least one of the vias, one or more additional dielectric layers lying over the metal conductors and the first dielectric layer, wherein a top layer of the one or more dielectric layers has openings with metalization underneath coupled to at least one of the metal conductors, and solder bumps protruding from each of the openings.
Abstract:
A semiconductor package (10), said package comprising: a substrate (12); a cavity (14) formed within the substrate; a semiconductor chip (16) situated in the cavity. The semiconductor chip comprises a plurality of circuit contacts (30) extending from the semiconductor chip, proximate a periphery of the cavity. Conductive traces (32) are formed on the top surface of the substrate, and electrical interconnections (34) bridge the circuit contacts of the semiconductor chip to the conductive traces of the substrate. Conveniently, the semiconductor chip may be flush with the top surface of the substrate. The circuit contacts may extend from the top surface of the semiconductor chip.
Abstract:
A package includes a substrate with a recess in which a light emitting element is mounted. A surface of the substrate forms an exterior surface of the package. A lid may be attached to the substrate to define a sealed region in which the light emitting element is mounted. The lid is transparent to a wavelength of light emitted by the light emitting element. Electrostatic discharge protection circuitry in the substrate is electrically coupled to the light emitting element.
Abstract:
A magnetically directed, self-assembled structure has a first body. The first body includes a single magnet or plurality of magnets disposed thereon to form a spatially variable magnetic field in a first predetermined pattern. A second body has a single magnet or plurality of magnets disposed thereon to form a spatially variable magnetic field in a second predetermined pattern. The second predetermined pattern is complementary to the first pattern. The first body is attracted to the second body with an attractive force greater than a mixture force such that the first body and second body are fully aligned to each other and bonded together.
