  • Patent number: 7880305
    Abstract: The invention is the technology of providing a packaging intermediate product that can serve as an interface substrate that is to be positioned between different circuitry types where the dimensions are approaching the sub 100 micrometer range. The invention involves a dielectric wafer structure where the first and second area surfaces of the wafer are separated by a distance that is of the order of the electrical via design length, and an array of spaced vias through the wafer arranged with each via filled with metal surrounded by a chemical metal deposition promoting layer with each via terminating flush with a wafer surface.

  • Patent number: 7823278
    Abstract: An interposer having one or more hollow electrical contact buttons disposed in a carrier. The interposer is formed by disposing sacrificial posts in vias of the carrier. The electrical contact buttons are formed on the sacrificial posts by a metallizing process in desired pattern using a mask. The sacrificial posts are made of a material that thermally decomposes upon application of heat without altering the carrier or the electrical contact buttons.

  • Patent number: 7688095
    Abstract: Flexible and rigid interposers for use in the semiconductor industry and methods for manufacturing the same are described. Auto-catalytic processes are used to minimize the costs associated with the production of flexible interposers, while increasing the yield and lifetime. Electrical contact regions are easily isolated and the risk of corrosion is reduced because all portions of the interposer are plated at once. Leads projecting from the flexible portion of the interposers accommodate a greater variety of components to be tested. Rigid interposers include a pin projecting from a probe pad affixed to a substrate. The rigidity of the pin penetrates oxides on a contact pad to be tested. Readily available semiconductor materials and processes are used to manufacture the flexible and rigid interposers according to the invention. The flexible and rigid interposers can accommodate pitches down to 25 ?m.

  • Publication number: 20090298292
    Abstract: A process for overcoming extreme topographies by first planarizing a cavity in a semiconductor substrate in order to create a planar surface for subsequent lithography processing. As a result of the planarizing process for extreme topographies, subsequent lithography processing is enabled including the deposition of features in close proximity to extreme topographic surfaces (e.g., deep cavities or channels) and, including the deposition of features within a cavity. In a first embodiment, the process for planarizing a cavity in a semiconductor substrate includes the application of dry film resists having high chemical resistance. In a second embodiment, the process for planarizing a cavity includes the filling of cavity using materials such as polymers, spin on glasses, and metallurgy.
