Abstract:
In one embodiment, the present invention includes a method of mounting a semiconductor device to a first side of a circuit board; and mounting at least one voltage regulator device to a second side of the circuit board, the second side opposite to the first side. The voltage regulator devices may be output filters, inductors, capacitors, and the like. In certain embodiments, the devices may be located directly underneath the semiconductor device.
Abstract:
In a stacked semiconductor package, since electric power is supplied to a second semiconductor package through a first semiconductor package, a power supply path becomes complicated and fluctuation of its inductance becomes large, whereby power bounce occurs to reduce signal quality and also prevent high speed signal communication. Therefore, according to the present invention, a first solder ball group for joint to a printed wiring board is attached to a second layer of the first semiconductor package, and a second solder ball group for joint to the first semiconductor package and a solder group for power supply for direct joint to the printed wiring board are provided on the second layer of the second semiconductor package, whereby electric power can be directly supplied from the printed wiring board.
Abstract:
A method of manufacturing a stackable package to create a 3-dimensional memory array using ball grid array technology. Specifically, memory chips are coupled to a preformed packages which have alignment features to allow for the stacking of the ball grid arrays. The alignment features are used to align and orient each package with respect to an adjacent package, substrate or printed circuit board. The alignment features also support the weight of the adjacent package during solder ball reflow to maintain stack height and parallelism between packages. Each memory device is serially connected to the adjacent memory device through the vias and solder balls on each package.

Abstract:
A circuit component module includes a heat-releasing plate, a resin film stacked on a surface of the heat-releasing plate, an electronic component embedded in the first resin film and partially in contact with the heat-releasing plate, and a wiring pattern embedded in the surface of the first resin film opposite the heat-releasing plate. The wiring pattern forms a circuit in combination with the electronic component.
Abstract:
A stack package for a high density memory module includes at least one memory chip, an ASIC and an interposer, wherein the interposer comprises a first surface having contacts arranged in electrical communication with corresponding contacts on the ASIC and a second, substantially opposite surface including contacts arranged in electrical communication with corresponding contacts on a PCB. The at least one memory chip is dimensioned to fit within a cutout section in the interposer.
Abstract:
Disclosed are an integrated circuit component capable of simply mounting at low cost a chip part which adjusts impedance of wiring patterns as well as capable of effectively reducing switching noise from an integrated circuit, and a method for mounting the chip part. The integrated circuit component of the present invention has a constitution that a bypass capacitor is mounted on a wiring board side of a gap between the wiring board and an LSI chip. Therefore, as compared with a case where the capacitor is mounted on the LSI chip side, a transmission path through the capacitor can be extremely shortened. As a result, inductance components of the feeder line can be reduced, so that a response delay of power transmitted through the feeder line can be sufficiently suppressed.
Abstract:
A method and apparatus for fabricating a three dimensional array of semiconductor chips is disclosed. The method uses a multiple step fabrication process that automates the surface mounting of semiconductor chips with unique chip carriers to achieve the three dimensional array of chips. The method can include the steps of depositing solder on one or more chip modules, placing and interconnecting low-cost components on the chip modules, and storing the preprocessed chip modules in pallets or in a tape and reel. Later these chip carriers may then be mounted on a circuit board, possibly over; for example, low and/or high cost components and then populated with low and/or high cost components. The apparatus includes a unique stackable chip module pallet and print fixture pedestal.
Abstract:
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.
