  • Patent number: 6429755
    Abstract: Integrated circuit fabrication technique for constructing novel MEMS devices, specifically band-pass filter resonators, in a manner compatible with current integrated circuit processing, and completely encapsulated to optimize performance and eliminate environmental corrosion. The final devices may be constructed of single-crystal silicon, eliminating the mechanical problems associated with using polycrystalline or amorphous materials. However, other materials may be used for the resonator. The final MEMS device lies below the substrate surface, enabling further processing of the integrated circuit, without protruding structures. The MEMS device is about the size of a SRAM cell, and may be easily incorporated into existing integrated circuit chips. The natural frequency of the device may be altered with post-processing or electronically controlled using voltages and currents compatible with integrated circuits.

  • Patent number: 6428886
    Abstract: A method for fabricating an object to attenuate thermal sensation when handling the object at non-body temperature, and an object fabricated in accord with the method. There is first provided a substrate which has a first surface subject to handling. There is then formed upon the first surface of the substrate a coating. The coating has an optimal density, an optimal thermal conductivity and an optimal thickness such that when the substrate having the coating formed thereupon is equilibrated at a non-body temperature differing from a body temperature and the coating is subsequently contacted with a body at the body temperature during handling, the temperature of the surface of the coating at a contact point of the body with the coating changes precipitously to a temperature near the body temperature and subsequently returns towards the non-body temperature at a rate which permits handling of the coating at the location of the first surface of the substrate by the body with attenuated thermal sensation.

  • Patent number: 6428894
    Abstract: Disclosed is vapor deposited BARC and method of preparing tunable and removable antireflective coatings based on amorphous carbon films. These films can be hydrogenated, fluorinated, nitrogenated carbon films. Such films have an index of refraction and an extinction coefficient tunable from about 1.4 to about 2.1 and from about 0.1 to about 0.6, respectively, at UV and DUV wavelengths, in particular 365, 248 and 193 nm. Moreover, the films produced by the present invention can be deposited over device topography with high conformality, and they are etchable by oxygen and/or a fluoride ion etch process. Because of their unique properties, these films can be used to form a tunable and removable antireflective coating at UV and DUV wavelengths to produce near zero reflectance at the resist/BARC coating interface. This BARC greatly improves performance of semiconductor chips.

  • Patent number: 6425518
    Abstract: There is provided a method for applying solder to an element on a surface of a substrate. The method comprises the steps of (a) placing a mold over the surface, where the mold includes a conduit that contains the solder, and (b) heating the solder to a molten state so that the solder flows from the conduit onto the element. The conduit enjoys two degrees of horizontal freedom with respect to the surface such that the conduit becomes substantially aligned with the element when the solder is in the molten state. There is also provided a system for applying solder to an element on a surface of a substrate.

  • Patent number: 6418401
    Abstract: A method for reducing the computation time and improving the productivity in designing high-performance microprocessor chips that have no failures—due to crosstalk noise. The technique allows a very fast calculation of tables of frequency-dependent circuit parameters needed for accurate crosstalk prediction on lossy on-chip interconnections. These tables of parameters are the basis for CAD tools that perform crosstalk checking on >10K critical nets on typical microprocessor chips. A fast table generation allows for rapid incorporation of design or processing changes and transition to more advanced technologies.
