  • Patent number: 8338229
    Abstract: A method of forming a stackable plasma cleaned via package includes forming interconnection balls on terminals. The interconnection balls are encapsulated in a package body, e.g., molding compound. Via apertures are formed through the package body to expose the interconnection balls, wherein a contamination is formed on the interconnection balls. The contamination is removed using a plasma cleaning process. By removing the contamination, robust reflow of the interconnection balls is insured thus maximizing yield. Further, the plasma cleaning process is a cost efficient high volume process with no adverse effect on package reliability.

  • Patent number: 8133761
    Abstract: A semiconductor system (200) of one or more semiconductor interposers (201) with a certain dimension (210), conductive vias (212) extending from the first to the second surface, with terminals and attached non-reflow metal studs (215) at the ends of the vias. A semiconducting interposer surface may include discrete electronic components or an integrated circuit. One or more semiconductor chips (202, 203) have a dimension (220, 230) narrower than the interposer dimension, and an active surface with terminals and non-reflow metal studs (224, 234). One chip is flip-attached to the first interposer surface, and another chip to the second interposer surface, so that the interposer dimension projects over the chip dimension. An insulating substrate (204) has terminals and reflow bodies (242) to connect to the studs of the projecting interposer.

  • Patent number: 8030137
    Abstract: A semiconductor device with a first (101) and a second (111) semiconductor chip assembled on an insulating flexible interposer (120). The interposer, preferably about 25 to 50 ?m thick, has conductive traces (121), a central planar rectangular area and on each side of the rectangle a wing bent at an angle from the central plane. The central area has metal studs (122, 123) on the top and the bottom surface, which match the terminals of the chips, further conductive vias of a pitch center-to-center about 50 ?m or less. The side wings have contact pads (130) with metallic connectors (131) on the bottom surface; the connectors may be solder balls, metal studs, or anisotropic conductive films. The second chip is adhesively attached to a substrate, whereby the interposer faces away from the substrate. The interposer side wings have a convex bending (150) downwardly along the second chip and a concave bending (151) over the substrate; the side wing connectors are attached to the matching substrate sites.

  • Publication number: 20110075306
    Abstract: A packaged semiconductor device (200) with a substrate (220) having, sandwiched in an insulator (221), a flat sheet-like sieve member (240) made of a non-linear material switching from insulator to conductor mode at a preset voltage. Both member surfaces are free of indentations; the member is perforated by through-holes, which are grouped into a first set (241) and a second set (242). Metal traces (251) over one member surface are positioned across the first set through-holes (241); each trace is connected to a terminal on the substrate top and, through the hole, to a terminal on the substrate bottom. Analogous for metal traces (252) over the opposite member surface and second set through-holes (242). Traces (252) overlap with a portion of traces (252) to form the locations for the conductivity switches, creating local ultra-low resistance bypasses to ground for discharging overstress events.

  • Publication number: 20110011424
    Abstract: A process flow employing a liquid cleaning agent (510) such as flux to penetrate the interface between the glassy coats (402) and the surface of metal (120) and to delaminate the coats from the metal, and then, at elevated temperatures, to use the agent's vapor pressure to break up the glassy coats into smaller pieces (403). The glassy coats are prevented by their low density to penetrate into the molten solder. Finally, at ambient temperature, the floating filler debris is water-washed and rinsed away. Cleaning agents include low-viscosity liquids (oils) and flux, which do not decompose at elevated temperatures and are mixed with components operable to provide, at the elevated temperatures, the fumes for sufficient vapor pressure to break up and dislodge the coats from the metal contacts.
