  • Patent number: 8008763
    Abstract: A stacked electronic component comprises a first electronic component adhered on a substrate via a first adhesive layer, and a second electronic component adhered by using a second adhesive layer thereon. The second adhesive layer has a two-layer structure formed by a same material and having different modulus of elasticity. The second adhesive layer of the two-layer structure has a first layer disposed at the first electronic component side and a second layer disposed at the second electronic component side. The first layer softens or melts at an adhesive temperature. The second layer maintains a layered shape at the adhesive temperature. According to the stacked electronic component, occurrences of an insulation failure and a short circuiting are prevented, and in addition, a peeling failure between the electronic components, an increase of a manufacturing cost, and so on, can be suppressed.

  • Patent number: 8004075
    Abstract: Use of Pb-free solder has become essential due to the environmental problem. A power module is formed by soldering substrates with large areas. It is known that in Sn-3Ag-0.5Cu which hardly creeps and deforms with respect to large deformation followed by warpage of the substrate, life is significantly shortened with respect to the temperature cycle test, and the conventional module structure is in the situation having difficulty in securing high reliability. Thus, the present invention has an object to select compositions from which increase in life can be expected at a low strain rate. In Sn solder, by doping In by 3 to 7% and Ag by 2 to 4.5%, the effect of delaying crack development at a low strain rate is found out, and as a representative composition stable at a high temperature, Sn-3Ag-0.5Cu-5In is selected. Further, for enhancement of reliability, a method for partially coating a solder end portion with a resin is shown.

  • Publication number: 20110115101
    Abstract: An electronic circuit includes at least two organic components interconnected by conductor tracks and having a common carrier substrate. The components and the conductor tracks are formed from layer portions. An uppermost layer portion, remote from the carrier substrate, of the electronic circuit is of a patterned configuration comprising an electrically conducting material. The patterned uppermost layer portion on its side remote from the carrier substrate is provided with at least one protective layer arranged in congruent relationship with the uppermost layer portion. The at least two organic components include at least one first component of a first component type and at least one second component of a second component type different therefrom. Components of the same component type are respectively protected by a protective layer of the same composition and/or the same structure corresponding to that component type and differing from one another according to the corresponding component type.

  • Patent number: 7943412
    Abstract: A method of formation of a microelectromechanical system (MEMS) resonator or filter which is compatible with integration with any analog, digital, or mixed-signal integrated circuit (IC) process, after or concurrently with the formation of the metal interconnect layers in those processes, by virtue of its materials of composition, processing steps, and temperature of fabrication is presented. The MEMS resonator or filter incorporates a lower metal level, which forms the electrodes of the MEMS resonator or filter, that may be shared with any or none of the existing metal interconnect levels on the IC. It further incorporates a resonating member that is comprised of at least one metal layer for electrical connection and electrostatic actuation, and at least one dielectric layer for structural purposes. The gap between the electrodes and the resonating member is created by the deposition and subsequent removal of a sacrificial layer comprised of a carbon-based material.

  • Publication number: 20110108967
    Abstract: A semiconductor chip grid array package includes a die attach pad and a plurality of connector pads. A semiconductor die is mounted on the die attach pad, the semiconductor die having external connection terminals electrically connected respectively to the connector pads. An encapsulating material encapsulates the die and connector pads. A stud protrudes from each of the connector pads for providing an external electrical contact for the semiconductor chip grid array package. Each of the connector pads and respective studs are formed from an electrically conductive sheet. The connector pads have a thickness of at least 60% of the thickness of the conductive sheet and the respective studs have a thickness of no more than 40% of the thickness of the conductive sheet.

  • Patent number: 7939383
    Abstract: A semiconductor package and a fabrication method thereof are provided in which a dielectric material layer formed with a plurality of openings is used and a solder material is applied into each of the openings. A first copper layer and a second copper layer are in turn deposited over the dielectric material layer and solder materials, and the first and second copper layers are patterned to form a plurality of conductive traces each of which has a terminal coated with a metal layer. A chip is mounted on the conductive traces and electrically connected to the terminals by bonding wires, with the dielectric material layer and solder materials being exposed to the outside. This package structure can flexibly arrange the conductive traces and effectively shorten the bonding wires, thereby improve trace routability and quality of electrical connection for the semiconductor package.
