  • Publication number: 20080094081
    Abstract: A system performs continuous full linear scan of a flat media. The system includes, in part, a chuck, and at least first, second and third gantries. The chuck is adapted to support the flat media during the test. The first gantry includes at least one linear array of non-contacting sensors that spans the width of the flat media and is adapted to move across an entire length of the flat media. Each of the second and third gantries includes a probe head that spans the width of the flat media and each is adapted to apply an electrical signal to the flat media. Each probe head is further adapted to move along a direction substantially perpendicular to the surface of the flat media during the times when the first gantry is in motion and while test signals are being continuously applied.

  • Patent number: 7321621
    Abstract: The invention describes a number of differential, balanced high-speed circuits that permit the design of a receiver with Electronic Dispersion Compensation (EDC) on a single semiconductor substrate, including the functions of an analog Fast Forward Equalizer (FFE), a Clock and Data Recovery, a Decision Feedback Equalizer (DFE), enhanced by additional circuits that permit control of the slicing level to compensate for pulse distortion, and control of the phase offset to set the optimal eye sampling time when a distorted signal is received. To provide the utmost speed of operation, all circuits including the phase locked loop, operate as differential circuits which include a number of improvements in the design of the charge pump, the decision feedback equalizer, the slicing level control, and others.

  • Publication number: 20070254165
    Abstract: A method for manufacturing a poly- or microcrystalline silicon layer on an insulator comprises a silicon containing insulator, growing a thin adhesion promoting layer comprising amorphous silicon onto it and further growing a poly- or microcrystalline silicon layer onto the adhesion promoting layer. Such a sequence of layers, deposited with a PECVD method, shows good adhesion of the poly- or microcrystalline silicon on the base and is advantageous in the production of semiconductors, such as thin film transistors.

  • Patent number: 7127830
    Abstract: A method and apparatus for cleaning, rinsing and drying a reticle used in semiconductor device manufacturing, tilts the reticle during the drying process to prevent water from the rinsing process from collecting and remaining on the reticle. The rectangularly shaped reticle is held in a carrier and the top and bottom edges of the reticle may form an angle of at least about 8° with the horizontal to maximize drying efficiency, when the carrier is placed on a horizontal surface or suspended from above.
