  • Patent number: 7122456
    Abstract: An input output ring for a semiconductor device is disclosed that uses power buffers having widths that vary from the widths of the input and output buffers. In one embodiment, the pitches between bond pads are the same, in another embodiment the pitches between the bond pads can vary. In another embodiment, the number of bond pads is greater than the number of associated active buffer areas. By connecting two power bond pads to a common buffer the inductance associated with the buffer is reduced, thereby reducing the number of active buffers needed to be dedicated to providing power to the semiconductor device.

  • Patent number: 7105385
    Abstract: A field programmable gate array is described for use in a semiconductor chip such as a VLSI chip. The array is provided with variable wire-through porosity to allow for optimum chip-level routing through the array. This is achieved by dividing the array into blocks which can be individually assessed for required porosity. Then blocks that have been prefabricated with differing porosities are placed in the macro to optimize local chip level routing. The routing of wires is determined by developing a chip floor plan to include early timing allocation and a proposed placement of the array. The floor plan is then overlaid with critical logical wiring nets. From this, an initial selection of blocks is made based on proposed wiring density, and the macro is assembled with the blocks strategically placed therein. The procedure is likewise applicable to other types of densely obstructed cores embedded with a chip.

  • Patent number: 6855572
    Abstract: Systems and methods for packaging integrated circuit chips in castellation wafer level packaging are provided. The active circuit areas of the chips are coupled to castellation blocks and, depending on the embodiment, input/output pads. The castellation blocks and input/output pads are encapsulated and held in place by an encapsulant. When the devices are being fabricated, the castellation blocks and input/output pads are sawed through. If necessary, the wafer portion on which the devices are fabricated may be thinned. The packages may be used as a leadless chip carrier package or may be stacked on top of one another. When stacked, the respective contacts of the packages are preferably coupled. Data may be written to, and received from, packaged chips when a chip is activated. Chips may be activated by applying the appropriate signal or signals to the appropriate contact or contacts.

  • Patent number: 6815322
    Abstract: The present invention provides a technology capable of shortening a TAT of a microcomputer with a nonvolatile memory built therein and achieving a reduction in cost. Flash ROMs comprising memory cells each substantially identical in structure to each of memory cells of a flash memory are formed in their corresponding chips lying in a wafer. Subsequently, memory information is written into each of the memory cells of the flash ROM in a probe test process. Thereafter, the memory information written into the memory cell thereof is made unreprogrammable to thereby disable rewriting of the post-shipment memory information. Thus, the shortening of a TAT can be achieved as compared with a mask ROM built-in microcomputer, and management and fabrication costs can be reduced.

  • Patent number: 6806178
    Abstract: A gate insulating film, a gate electrode, a gate-top protection film, LDD layers and nitride film sidewalls are formed on a semiconductor substrate. Source/drain regions are formed in the semiconductor substrate. After deposition of an interlayer insulating film on the resultant substrate, a hole is formed through the interlayer insulating film and the gate-top protection film to reach the gate electrode, and a gate contact is formed by filling the hole. The gate-top protection film has an opening exposing part of a portion of the area on the top surface of the gate electrode other than the region in contact with the gate contact. This facilitates external diffusion of hydrogen during annealing, or recovery from a fixed level and a damage layer during sintering.
