  • Patent number: 8866308
    Abstract: Embodiments that allow both high density and low density interconnection between microelectronic die and motherboard via Direct Chip Attach (DCA) are described. In some embodiments, microelectronic die have a high density interconnect with a small bump pitch located along one edge and a lower density connection region with a larger bump pitch located in other regions of the die. The high density interconnect regions between die are interconnected using an interconnecting bridge made out of a material that can support high density interconnect manufactured into it, such as silicon. The lower density connection regions are used to attach interconnected die directly to a board using DCA. The high density interconnect can utilize current Controlled Collapsed Chip Connection (C4) spacing when interconnecting die with an interconnecting bridge, while allowing much larger spacing on circuit boards.

  • Patent number: 7411304
    Abstract: An interconnect for testing a semiconductor component includes a substrate, and interconnect contacts on the substrate configured to electrically engage component contacts on a semiconductor component. Each interconnect contact includes a compliant conductive layer formed as a conductive spring element. In addition, the complaint conductive layer includes a tip for engaging the component contact and a spring segment portion for resiliently supporting the tip. A method for fabricating the interconnect includes the steps of shaping the substrate, forming a conductive layer on a shaped portion of the substrate and removing at least some of the shaped portion. The shaped portion can comprise a raised step or dome, or a shaped recess in the substrate. The conductive layer can comprise a metal, a conductive polymer or a polymer tape can include a penetrating structure or penetrating particles.

  • Patent number: 7375421
    Abstract: Thinning and stacking are essential for circuit modules used for mobile devices of various kinds, smart cards, memory cards and the like. These demands make the manufacture of the circuit modules more complicated or less reliable due to delamination. A circuit module of a multilayer structure is provided which is formed by embedding semiconductor chips and passive components in a sheet made from a thermoplastic resin; folding a module sheet, which is formed of circuit blocks provided with wiring patterns thereon, at the boundaries of the circuit blocks so as to be stacked into layers; and thermal-bonding and integrating the module sheet by applying heat and pressure. As a result, a highly reliable circuit module can be manufactured in a simple manner.

  • Patent number: 7112866
    Abstract: The invention provides a new multilevel interconnect structure of air gaps in a layer of IMD. A first layer of dielectric is provided over a surface; the surface contains metal points of contact. Trenches are provided in this first layer of dielectric. The trenches are filled with a first layer of nitride or disposable solid and polished. A second layer of dielectric is deposited over the first layer of dielectric. Trenches are formed in the second layer of dielectric, a second layer of nitride or disposable solid is deposited over the second layer of dielectric. The layer of nitride or disposable solid is polished. A thin layer of oxide is deposited over the surface of the second layer of dielectric. The thin layer of oxide is masked and etched thereby creating openings in this thin layer of oxide, these openings align with the points of intersect of the trenches in the first layer of dielectric and in the second layer of dielectric. The nitride or removable solid is removed from the trenches.

  • Patent number: 7102243
    Abstract: A mask blank has a plurality of pattern formation regions in which mask circuit patterns are to be formed, and a supporting region in which any mask circuit pattern is not to be formed. The supporting region is provided for holding the plurality of pattern formation regions while separating the plurality of pattern formation regions from each other. The supporting region has first and second alignment marks. Exposure of a mask made from the mask blank for forming mask circuit patterns thereon is performed on the basis of the first alignment marks, and exposure of a substrate for forming circuit patterns thereon is performed on the basis of the second alignment marks. With this configuration, a mask used for charged particle beam reduction-and-division transfer exposure can be highly accurately produced at a low cost, and exposure of a substrate can be highly accurately performed by using the mask.
