Abstract:
A semiconductor package is disclosed including a leadframe, memory die and controller die, one or more of which are customized to facilitate electrical connection of the memory and controller die bond pads to the contact pads of the host device via the leadframe. By customizing one or more of the leadframe, memory die and controller die, an interposer layer normally required to connect the die in the semiconductor package with a host device may be omitted.
Abstract:
Methods of forming integrated circuit packages having an LED molded into the package, and the integrated circuit package formed thereby. An integrated circuit including one or more semiconductor die, passive components and an LED may be assembled on a panel. The one or more semiconductor die, passive components and LED may all then be encapsulated in a molding compound, and the integrated circuits then singularized to form individual integrated circuit packages. The integrated circuits are cut from the panel so that a portion of the lens of the LED is severed during the singularization process, and an end of the lens remaining within the package lies flush with an edge of the package to emit light outside of the package.
Abstract:
A method of fabricating a leadframe-based semiconductor package, and a semiconductor package formed thereby, are disclosed. The semiconductor package includes a leadframe and one or more semiconductor die affixed to a die paddle of the leadframe. The leadframe is formed with a plurality of electrical terminals that get surface mounted to a host PCB. The leadframe further includes one or more extended leads, at least one of which includes an electrically conductive island which gets surface mounted to the host PCB with the electrical terminals. The islands effectively increase the number terminals within the package without adding footprint to the package.
Abstract:
A semiconductor package including a plurality of stacked semiconductor die, and methods of forming the semiconductor package, are disclosed. In order to ease wirebonding requirements on the controller die, the controller die may be mounted directly to the substrate in a flip chip arrangement requiring no wire bonds or footprint outside of the controller die. Thereafter, a spacer layer may be affixed to the substrate around the controller die to provide a level surface on which to mount one or more flash memory die. The spacer layer may be provided in a variety of different configurations.

Abstract:
A low profile USB flash memory device, and methods of forming same, are disclosed. The USB flash memory device includes an integrated circuit memory portion and a USB connector. The memory portion and the USB connector may be integrally formed on the same substrate. The USB flash memory device includes a substrate on which is mounted one or more flash memory die, a controller die, passive components and an LED for indicating when the memory is being accessed. In contrast to prior art USB memory devices which used TSOP packages mounted on a printed circuit board, the semiconductor die of the present invention are affixed to the substrate and wire bonded in a SIP configuration. Omitting the encapsulated TSOP packages allows a reduction in the overall thickness of the USB flash memory device.

Abstract:
A system of micro balls is disclosed for coupling an electronic component to a printed circuit board. The micro balls have a small diameter, and each contact pad may include an array of two or more micro balls. An example of a micro ball may include a polymer core, surrounded by a copper layer, which is in turn surrounded by a layer of solder.
