  • Publication number: 20120241946
    Abstract: A semiconductor device has a semiconductor die with a plurality of bumps formed over contact pads on a surface of the semiconductor die. The bumps can have a fusible portion and non-fusible portion. A plurality of conductive traces is formed over a substrate with interconnect sites having a width greater than 20% and less than 80% of a width of a contact interface between the bumps and contact pads. The bumps are bonded to the interconnect sites so that the bumps cover a top surface and side surface of the interconnect sites. An encapsulant is deposited around the bumps between the semiconductor die and substrate. The conductive traces have a pitch as determined by minimum spacing between adjacent conductive traces that can be placed on the substrate and the width of the interconnect site provides a routing density equal to the pitch of the conductive traces.

  • Patent number: 8273587
    Abstract: An underfill technique for LEDs uses compression molding to simultaneously encapsulate an array of flip-chip LED dies mounted on a submount wafer. The molding process causes liquid underfill material (or a softened underfill material) to fill the gap between the LED dies and the submount wafer. The underfill material is then hardened, such as by curing. The cured underfill material over the top and sides of the LED dies is removed using microbead blasting. The exposed growth substrate is then removed from all the LED dies by laser lift-off, and the underfill supports the brittle epitaxial layers of each LED die during the lift-off process. The submount wafer is then singulated. This wafer-level processing of many LEDs simultaneously greatly reduces fabrication time, and a wide variety of materials may be used for the underfill since a wide range of viscosities is tolerable.

    Abstract: A flash memory card and methods of manufacturing same are disclosed. The card includes a semiconductor package fabricated to receive a single-sided or double-sided lid. A surface of the semiconductor package may be formed with holes, trenches and/or pockmarks. After the holes, trenches and/or pockmarks are formed, a lid may be attached to the package surface in an injection molding process. During the injection molding process, the molten plastic flows into the holes, trenches and/or pockmarks to interconnect with the surface of the semiconductor package. Thus, when the molten plastic hardens, the holes, trenches and/or pockmarks ensure that the lid remains firmly attached to semiconductor package.

  • Patent number: 8216886
    Abstract: A method for assembling a semiconductor package includes a rapid cooling step after post mold curing of an encapsulation material. The rapid cooling step includes blowing chilled, compressed air over the package for about two minutes. The rapid cooling step does not require any clamping pressure be simultaneously applied to the package. The rapid cooling step reduces a temperature of the encapsulation material from a curing temperature to the cooled temperature within a maximum period of less than five minutes. By using rapid cooling, as opposed to cooling the package under a clamping pressure with ambient air, package warpage due to CTE mismatches is prevented.
