  • Patent number: 8028254
    Abstract: The manufacturability of a lithographic mask employed in fabricating instances of a semiconductor device is determined. Target edge pairs are selected from mask layout data of the lithographic mask, for determining a manufacturing penalty in making the lithographic mask. The mask layout data includes polygons, where each polygon has a number of edges. Each target edge pair is defined by two of the edges of one or more of the polygons. The manufacturability of the lithographic mask, including the manufacturing penalty in making the lithographic mask, is determined. Determining the manufacturing penalty is based on the target edge pairs as selected. Determining the manufacturability of the lithographic mask uses continuous derivatives characterizing the manufacturability of the lithographic mask on a continuous scale. The manufacturability of the lithographic mask is output. The manufacturability of the lithographic mask is dependent on the manufacturing penalty in making the lithographic mask.

  • Publication number: 20110231803
    Abstract: Optical wave data for a semiconductor device design is divided into regions. First wavefront engineering is performed on the wave data of each region, accounting for just the wave data of each region and not accounting for the wave data of neighboring regions of each region. The optical wave data of each region is normalized based on results of the first wavefront engineering. Second wavefront engineering is performed on the wave data of each region, based at least on the wave data of each region as has been normalized. The second wavefront engineering takes into account the wave data of each region and a guard band around each region that includes the wave data of the neighboring regions of each region. The second wavefront engineering can be sequentially performed by organizing the regions into groups, and sequentially performing the second wavefront engineering on the regions of each group in parallel.

  • Publication number: 20100153901
    Abstract: The manufacturability of a lithographic mask employed in fabricating instances of a semiconductor device is determined. Target edge pairs are selected from mask layout data of the lithographic mask to determine a manufacturing penalty in making the lithographic mask. The mask layout data includes polygons, where each polygon has edges, and where each target edge pair is defined by two of the edges of one or more of the polygons. The number of the target edge pairs is reduced to decrease computational volume in determining the manufacturing penalty in making the lithographic mask. The manufacturability of the lithographic mask, including the manufacturing penalty in making the lithographic mask, is determined based on the target edge pairs as reduced in number. The manufacturability of the lithographic mask is output. The manufacturability of the lithographic mask is dependent on the manufacturing penalty in making the lithographic mask.

  • Patent number: 7103551
    Abstract: A described computer network includes a first computer system and a second computer system. The first computer system transmits screen image information and corresponding speech information to the second computer system. The screen image information includes information corresponding to a screen image intended for display within the first computer system. The speech information conveys a verbal description of the screen image. When the screen image includes one or more objects (e.g., menus, dialog boxes, icons, and the like) having corresponding semantic information, the speech information includes the corresponding semantic information. The second computer system responds to the speech information by producing an output (e.g., human speech via an audio output device, a tactile output via a Braille output device, and the like). The semantic information conveyed by the output allows a visually-impaired user of the second computer system to know intended purposes of the objects.

  • Patent number: 6448958
    Abstract: To make window systems which are widely used in personal computers and applications for personal computers operable in a portable information terminal which does not have a sufficient processing capability, input information such as a key input from operator generated in a portable information terminal 210 is sent to a remote supporting server 240 where it executes or simulates an arbitrary window system which is free from restriction of functions to generate a rendering image. The supporting server then converts the rendering image to an image suitable to the portable information terminal and sends it back to the portable information terminal 210 as a rendering instruction. The portable information terminal 210 receives the rendering instruction of this optimized image for display.

  • Patent number: 6377271
    Abstract: The image data transferring apparatus of this invention determines that the change in the image is very small when a change in the image is not detected during a given time period, for example, and generates transmission data which causes image data displaying a full color image of, for example, 24 bits per pixel to be displayed in the receiving side in a relatively small number of frames in a unit time for transmission. Conversely, the image data transferring apparatus transmits reduced color data which is reduced from 24 bits per pixel to 4 bits per pixel in a relatively large number of frames in a unit time to the receiving side when it is determined that many changes are included in the image.

  • Patent number: 6286003
    Abstract: Control of a GUI screen at a server in a remote location is obtained without requiring the prior installment of special remote controlling software in a remote controlling machine. Remote controlling software is described in an HTML (HyperText Markup Language) file that is held by the server, and a remote controlling machine downloads it using a web browser. The downloaded remote controlling software is automatically activated and sends a request for the activation of remotely controlled software that is present in a remotely controlled server. The remote controlling machine then activates an event monitor, an event sender, a drawing command receiver and a drawing command analyzer, which are functions of the remote controlling software.
