摘要： A thin, small outline IC leadframe plastic package to be used to assemble high performance, high speed semiconductor memory IC devices such as dynamic random access memories (DRAM) having a high data transfer rate in the range of 1 GigaHertz. The package leadframe is electrically interconnected to the IC device input-output pads by either electrically conductive (e.g. solder) bumps that are flip-chip bonded to the IC device or by of an interposer. The interposer contains integral curled micro-spring contacts at opposite ends of conductive fan out traces. The interposer is attached to the leadframe bonding pads by way of tape automated bonding, soldering, or adhesive bonding. The leadframe that is interconnected to the IC device by the aforementioned flip-chip bumps or the interposer is encapsulated and trimmed to form either gull-wing style perimeter leads as a standard thin small outline package (TSOP) or wrap around leads as a micro-leadframe (MLF) package.

摘要： A high density memory card assembly having application for USB drive storage, flash and ROM memory cards, and similar memory card formats. A cavity is formed through a rigid laminate substrate. First and second digital memory devices (e.g., TSOP packages or bare semiconductor dies) are located within the cavity so as to be recessed relative to the top and bottom of the substrate. The recessed first and second memory devices are arranged in spaced, face-to-face alignment with one another within the cavity. The first and second memory devices are covered and protected by respective first and second memory packages that are located on the top and bottom of the substrate. By virtue of the foregoing, the memory package density of the assembly can be increased without increasing the height or area consumed by the assembly for receipt within an existing external housing.

摘要： A method for forming a conductive vias in a non-conductive substrate having a through-hole formed therein intermediate two side thereof. The method utilizes the steps of: applying gold paste to the through-hole so as to provide electrical conduction therethrough; and under firing the gold paste when a thin conductive film is present upon the substrate and fully firing the gold paste when no thin conductive film is present on the substrate. Under firing the gold paste when a thin-film is present upon the substrate prevents degradation of the thin conductive film. Subsequent processing of the gold paste assures the integrity and reliability thereof. Thus, the gold paste provides enhanced conductivity and improved reliability, as compared to contemporary thin-film vias.

摘要： The present invention discloses a new substrate with two metal layer circuit structure and layout for semiconductor packaging. The speed and performance characteristics of the semiconductor device are optimized while the packaging structure is simplified by utilizing only one dielectric layer and conventional printed circuit board fabrication process. The difficulties encountered due to the complexities and higher cost of production required for the multiple layer and high density configuration are thus avoided. The improved circuit structure is achieved by implementing a segmented ring on one side of a substrate and a split plane on the other side thus forming a single layer substrate structure. The edges of the substrate are coated with metal layer to provide inter-layer connections. In addition to the benefits of high performance, low cost, the improved circuit structure and package layout provide flexibility allowing higher degree of freedom for selecting the location and number of input and output signal lines and connections to the ground and power planes from the semiconductor device.

摘要： A multi-directional infrared detector system provides multi-view or surround-view imaging which is particularly suited for use in tactical battlefield situations. The system utilizes a plurality of infrared detector arrays disposed in a generally circular configuration, each of the infrared detector arrays having a plurality of infrared detector elements formed thereon; a corresponding plurality of dedicated optics assemblies for forming images upon the infrared detector arrays; and at least one conductive conduit supporting layer having conductive conduits formed thereon. The conductive conduit support layer extends inwardly from each of the infrared detector arrays to a core defined by the infrared detector arrays. Signal conditioning circuitry is disposed generally at the core of the infrared detector arrays such that signals representative of the outputs of the infrared detector elements are communicated from the detector elements to the signal processing circuitry via the conductive conduits.

摘要： A high density, low profile, three dimensional memory module having multi-level semiconductor packages mounted on one or opposite sides of a printed wiring board. Each multi-level package of the memory module contains an upper level DRAM integrated circuit package that is surface mounted on the printed wiring board and at least one lower level DRAM integrated circuit package that is surface mounted on the printed wiring board below the upper level package, such that the upper and lower level packages are stacked one above the other. The upper level package is preferably a thin small outline package, and the lower level package is preferably a leadless chip scale package. The leads of the upper level package are of sufficient length so that the standoff height of the upper level package establishes a clearance thereunder in which to receive the lower level package. The lower level package is characterized by a smaller footprint and profile than the corresponding footprint and profile of the upper level package.

摘要： An infrared detector subarray having an integral filter assembly is comprised of a plurality of stacked modules defining an infrared detector focal plane subarray; a filter plate sized and configured to correspond to the infrared detector subarray; and a plurality of supports disposed intermediate the filter plate and the detector subarray for attaching the filter plate to the subarray such that the filter plate is in close proximity to the detector subarray. Scattering and crossstalk are minimized by positioning the filter plate in close proximity to the detector subarray. The supports may comprise planar members having a thickness of less than approximately 0.003 inch such that they may be disposed intermediate adjacent modules. The filter plate may further comprise a plurality of parallel stripes, each parallel stripe transmitting infrared radiation of a different frequency than that transmitted by adjacent stripes such that a focal plane array comprised thereof may be sensitive to infrared radiation at a plurality of frequencies. Forming the filter as an integral part of the subarrays eliminates the need to fabricate a single filter having a diameter of two feet or more. The infrared detector subarray and integral filter assembly of the present invention provide for the fabrication of a filter which is easier to fabricate, has a higher fabrication yield, is lighter in weight, has improved mechanical stability, and facilitates more reliable testing.
