    Abstract: Techniques are provided for efficient wafer layout, which include the use of an offset grid to optimize use of available wafer space. As such, the number of identical die that can be fabricated on the wafer can be increased, relative to a standard perpendicular grid. By adding additional registration marks, an increase in flexibility of where each row/column of fields can be printed is enabled. This increased level of freedom in-turn allows for the optimization of the number of die that each row/column can contain, and translates directly into an increase in the number of yielding die per wafer. In addition, techniques are provided that allow for the dicing of individual die in a non-Cartesian coordinated manner. However, conventional singulation techniques can be used as well, given attention to the offset grid lines.

    Abstract: A geometric diode, method and device applications are described. The geometric diode is produced including a device body formed from an electrically conductive material having an equilibrium mobile charge density, and having a device surface configuration. The material has a charge carrier mean free path with a mean free path length and the device body size is selected based on said the free path length to serve as an electrically conductive path between first and second electrodes delimited by the device surface configuration that is asymmetric with respect to a forward flow of current in a forward direction from the first electrode to the second electrode as compared to a reverse current flow in an reverse direction from the second electrode to the first electrode. A system includes an antenna for receiving electromagnetic radiation coupled with the geometric diode antenna to receive the electromagnetic radiation to produce an electrical response.

  • Patent number: 7816795
    Abstract: Synchronization between command and address signals commonly coupled to a plurality of memory devices to be operated in parallel and a clock signal coupled to the memory devices is achieved, while suppressing an increase in the clock wiring length. A semiconductor device has a data processing device mounted on a wiring substrate and a plurality of memory devices accessed in parallel by the data processing device. The data processing device outputs the command and address signals as a first frequency from command and address terminals, and outputs a clock signal as a second frequency from a clock terminal. The second frequency is set to multiple times of the first frequency, and an output timing equal to or earlier than a cycle starting phase of the clock signal output from the clock terminal can be selected to the command and address signals output from the command and address terminals.
