  • Patent number: 7879691
    Abstract: Exemplary embodiments provide methods and systems for assembling electronic devices, such as integrated circuit (IC) chips, using a release member having a phase change material. Specifically, IC elements/components can be selectively received, stored, inspected, repaired, and/or released in a scalable manner during the assembly of IC chips by inducing phase change of the phase change material. The release member can be flexible or rigid. In some embodiments, the release member can be used for a low cost placement of the IC elements in combination with an SOI (silicon on insulator) wafer and/or an intermediate transfer member. In other embodiments, the release member can be used for a low cost placement of the IC elements in combination with a release wafer.

  • Patent number: 7874474
    Abstract: A self-assembly process is disclosed for integrating free standing microcomponents onto a template having a plurality of binding sites, an interconnect network, and trapping structures disposed downstream of the binding sites. The self-assembly is accomplished by flowing a fluid medium containing the microcomponents over the template such that some of the microcomponents are trapped at binding sites. The template may be simultaneously (or subsequently) heated to melt a binder such as a solder spot at each of the binding sites, and then cooled to connect the trapped microcomponents to the interconnect network. In one embodiment, removable blocking elements are disposed upstream of some of the binding sites, for example formed from photoresist. After assembling a first set of microcomponents, the blocking elements are removed, and a second set of microcomponents in a fluid medium are flowed over the template for assembly into the newly unblocked binding sites.

  • Patent number: 7816182
    Abstract: A multichip integrated circuit apparatus includes first and second integrated circuit die mounted on opposite sides of a leadframe die paddle, with at least one of the integrated circuit die extending further toward the leads than does the die paddle. With this arrangement, the active circuit areas of both integrated circuit die can face in the same direction, and can be wire bonded to the same surfaces of the leads. This avoids wire bonding complications that are often encountered in multichip integrated circuit package designs.

  • Patent number: 7816793
    Abstract: One embodiment of the present invention provides a system for facilitating proximity communication between semiconductor chips. The system includes a base chip and a bridge chip, each of which includes an active face upon which active circuitry and signal pads reside, and a back face opposite the active face. The active face of the bridge chip is bonded to the active face of the base chip. Then, an identified portion of the active face of the bridge chip is thinned via etching and is removed by planarizing the back face of the bridge chip, thereby creating an opening in the bridge chip that exposes a portion of the active face of the base chip.

  • Patent number: 7811842
    Abstract: Methods for fabricating light-emitting diode (LED) array structures comprising multiple vertical LED stacks coupled to a single metal substrate is provided. The LED array structure may comprise two, three, four, or more LED stacks arranged in any configuration. Each of the LED stacks may have an individual external connection to make a common anode array since the p-doped regions of the LED stacks are all coupled to the metal substrate, or some to all of the n-doped regions of the LED stacks may be electrically connected to create a parallel LED array. Such LED arrays may offer better heat conduction and improved matching of LED characteristics (e.g., forward voltage and emission wavelength) between the individual LED stacks compared to conventional LED arrays.

    Abstract: A method for selectively processing a surface tension of a solder mask layer in a circuit board is provided. The method conducts surface tension processing to the flip-chip area and the non-flip-chip area of the solder mask layer in the circuit board. Therefore, the underfill used in packaging configures relative contact angles at the flip-chip area and the non-flip-chip area of the solder mask layer, respectively. In such a way, the present invention is adapted to solve the difficulties of the underfill void bulb and the overflowing contamination at the same time.
