  • Integrated wafer cassette metrology assembly
    Patent number: 6738142
    Abstract: An apparatus with one or more dimensions conforming to a wafer storage cassette used in semiconductor manufacturing which contains all or part of a sensor designed to measure a parameter of a wafer placed into the cassette. The intended use of the apparatus is in a process tool location normally occupied by a standard wafer cassette. By integrating all or part of the sensor into standard wafer storage cassette, a solution is provided whereby the same cassette and metrology system can be mechanically integrated into many process tools.

  • Digital printer for avoiding moire patterns by using a dithering mask and angular rotation between print head and print medium to simulate analog printer halftoning of color images
    Patent number: 6738162
    Abstract: A semi-digital printer includes a print head assembly that prints an image on a sheet of paper that has been mounted onto a turntable, and a rotating means which rotates the turntable so that the print head assembly ejects ink or toner onto the sheet of paper at one or more predetermined angles. The printing may be halftone or color. If the print head assembly includes more than one print head, the rotating means rotates the turntable to a different angle for each print head. By rotating the turntable in this manner, the printer records an image at any angle (0° to 360°) precisely (i.e., without having to perform the angular approximations required by conventional digital printers). As a result, a printed image of improved quality is produced. Alternatively, the semi-digital printer may be configured so that the print head assembly rotates relative to the paper.

  • Method of building a CMOS structure on thin SOI with source/drain electrodes formed by in situ doped selective amorphous silicon
    Patent number: 6734109
    Abstract: The present invention provides improved controllability of the lateral etch encroachment of silicon under the spacer, in light of the fact that the exemplary method, in accordance with the present invention, comprises the step of implanting neutral ions such as Ge or Ar into the source/drain regions. The implantation creates an amorphous silicon surface, and leaves a laterally extended amorphous layer under the spacer and a well defined amorphous/crystalline interface. The etch of silicon then extends laterally underneath the spacer, due to the higher etch rate of amorphous silicon and abrupt interface between amorphous and crystalline silicon.

  • Distributed application assembly
    Patent number: 6728750
    Abstract: A system and a method for developing and dynamically constructing multi-tiered distributed computing applications using a framework which allows the major elements involved in enterprise software applications, namely, the user interface, the data access, and the processing logic, to be independently developed. Moreover, the applications are dynamically created at time of use with pre-built software components or objects. The specifics of the applications such as functions, capabilities, user interface (UI) characteristics, etc., may depend on, for example, the user identity, the user preferences, and the terminal capability. Software development cost and turn-around time are reduced, promoting consistent UI design thus reducing user training cost, and allowing the applications to be dynamically created according to the user profile.

  • Conference terminal control device
    Patent number: 6728222
    Abstract: A multi-point control unit (MCU) for a multi-point connected conference system is disclosed in which to attain low power consumption and enhance sound quality, when a speaker detection circuit 4 judges that the number of conference terminals having transmitted a voiced compressed code is one, a first selector 6 directly transmits compressed voice to a second selector 16 without decoding the voice, and the second selector 16 outputs the compressed voice to a distribution circuit 18. Thereby, since a voice signal is transmitted to the conference terminal without passing through a decoder 8, and the like, the power necessary for a processing is reduced, and the deterioration of sound quality by the voice processing, and the like are prevented from occurring.
