In one embodiment, the fabrication method includes printing a patterned die attach material onto the backside of a wafer including an array of non-singulated microelectronic die each having an interior keep-out area, such as a central keep-out area. The die attach material, such as a B-stage epoxy, is printed onto the wafer in a predetermined pattern such that the die attach material does not encroaching into the interior keep-out areas. The wafer is singulated to produce singulated microelectronic die each including a layer of die attach material. The singulated microelectronic die are then placed onto leadframes or other package substrates with the die attach material contacting the package substrates.

  • Patent number: 8918990
    Abstract: A method of forming solder-less printed wiring boards includes attaching a electronic components to a workpiece using an adhesive material. A mold material is added to partially cover the electronic components to form a sub-assembly including the electronic components attached to the mold material and a planar surface on the workpiece side. At least tops of the electronic components extend beyond a height of the mold material. The adhesive material is removed to separate the workpiece and sub-assembly. A first prepreg dielectric is attached to the planar surface of the mold material. First vias are formed in the first prepreg dielectric to expose bondable contacts of the electronic components. The first vias are filled with electrically conductive plugs to provide connections to the bondable contacts of the electronic components. A circuit layer is formed on a surface of the first prepreg dielectric to provide contact to the first plugs.

  • Patent number: 8916416
    Abstract: A semiconductor device has a semiconductor die with a plurality of bumps formed on contact pads disposed over its active surface. An encapsulant is formed over the semiconductor die. An interconnect structure is formed over the semiconductor die and encapsulant. The semiconductor die is mounted to a translucent tape with the bumps embedded in the translucent tape. The translucent tape has layers of polyolefin, acrylic, and polyethylene terephthalate. A back surface of the semiconductor die undergoes backgrinding to reduce die thickness. The tape undergoes UV curing. A laminate layer is formed over the back surface of the semiconductor die. The laminate layer undergoes oven curing. The laminate layer is laser-marked while the tape remains applied to the bumps. The tape is removed after laser-marking the laminate layer. Alternately, the tape can be removed prior to laser-marking. The tape reduces die warpage during laser-marking.
