  • Sensor for measuring liquid contaminants in a semiconductor wafer fabrication process
    Patent number: 7696538
    Abstract: Liquid detection sensors are attached to both sides of a robotic arm end effector of a semiconductor wafer process system. The sensor mechanism or probe is situated on the front side and backside of the end effector, designed with electrical lines that are traced onto a polyester base material. The electrical lines are positioned in a serpentine formation. The high conductance of the sulfuric acid in the copper sulfate solution acts as the conductor between the traced lines. When the conductive liquid comes in contact with the traced lines, the lines short and the sensor activates or turns on.

  • Method for optimization of optical proximity correction
    Patent number: 7694268
    Abstract: A method of designing and forming a mask used for projecting an image of an integrated circuit design. After providing a mask element corresponding to a portion of a design of an integrated circuit layout, the method includes correcting the mask element using OPC techniques, and fracturing the OPC-corrected mask element into a plurality of polygonal segments. The method then includes identifying along an edge of the mask element a polygon edge having a thickness less than that which can be normally reproduced by a mask writer, and modifying configuration of the identified mask element segment to add or subtract length to an end of the polygon to create a corrected mask element having increased resolution by the mask writer. The method then includes using an electron beam or other mask writer to form a mask having the mask element with modified configuration.

  • Method for the manufacture of liquid-metal composite contact
    Patent number: 7686864
    Abstract: A method of manufacturing liquid-metal composite contacts, where fabric of high-melting metal based wire is in the form of a strip, rolled into a cylindrical workpiece, and installed into a matrix. The workpiece is then pressed, reduced in an environment of hydride hydrogen in a vacuum furnace, and soaked with low-melting metal or alloy, where the soaking of the structure is performed with three metals, tin (Sn), indium (In) and gallium (Ga) within three sequential stages lasting 10 to 20 minutes each, namely, the structure is first soaked with liquid tin at a temperature of 750 to 1150° C., then with liquid indium at the temperature of 750 to 1000° C., and third with liquid gallium at the temperature of 700 to 900° C. The amount of liquid tin, indium, and gallium is proportional to eutectic mixture and volume of the pores in the structure.

  • System for coloring a partially colored design in an alternating phase shift mask
    Patent number: 7687207
    Abstract: A method of designing an alternating phase shifting mask for projecting an image of an integrated circuit design. Phase units are binary colorable within each unit of the hierarchical circuit design, e.g., cell, an array, a net, or array of nets and/or cells, the phase shapes. The assignment of phases or colors within a hierarchical unit will be correctly binary colored to satisfy the lithographic, manufacturability and other design rules, referred to collectively as coloring rules. During assembly with other units, the coloring of phases in a hierarchical unit may change (e.g., be reversed or flipped), but the correct binary colorability of a hierarchical unit is preserved, which simplifies assembly of the integrated circuit layout.

  • Apparatus and method for steering transport vehicles in semiconductor processing
    Patent number: 7677180
    Abstract: A steering apparatus and method is implemented that allows high speed, clean, particle-free transport of a semiconductor wafer or lithographic reticle on a transport vehicle at various positions on the vehicle track, especially when entering and exiting turns. Three computer-controlled electro-magnets are mounted at the left, center, and right side of a front steering truck, and are energized to attract strategically placed permanent magnet material mounted on a side of the track where the vehicle enters or exits a turn. The transport vehicle can be levitated by an air cushion or travel on wheels, and controlled by electromotive or electromagnetic forces about the track. Using the steering electro-magnets as a LVDT, a computer processor monitors the location of the transport vehicle about the track.

  • Dual connector for an antenna element
    Patent number: 7670176
    Abstract: Two connection interfaces are combined in a single assembly for high frequency signal propagation of a GPS antenna. At least one connection interface is a constant impedance connector. The connector assembly allows for the application of o-rings and gaskets to be placed circumferentially about the radome to protect against environmental elements, mechanical shock and vibration. The first connection interface has a male plug on a first piece of a dual connector design, and a complementary female plug on a second piece. The second connection interface comprises a plug of any standard industry connector mounted on the second piece opposite the complementary female plug, and is configured to easily mate to a corresponding plug from a cable or other electronic equipment.

  • Alignment verification for C4NP solder transfer
    Patent number: 7666780
    Abstract: A method is provided for the making of interconnect solder bumps on a wafer or other electronic device. The method is particularly useful for the well-known C4NP interconnect technology and determines if any off-set resulted between the solder mold array and the wafer capture array during the transfer process. The amount of off-set enables the operator to adjust the transfer tool before solder transfer to compensate for the off-set caused by the transfer process and provides a more cost-effective and efficient solder transfer process. A solder reactive material surrounding the capture pads is used to determine where the solder reacts with the solder reactive material showing the off-set resulting from the transfer process. Copper is a preferred solder reactive material.

  • RFID wireless control of instant messaging
    Patent number: 7664820
    Abstract: A remote control instant messaging method and system for automatically activating an instant messaging session based upon remote detection of a user approaching a processor capable of executing an instant message system. The method and system also automatically deactivate the instant messaging session based upon remote detection of the user's absence from such processor and automatically re-activate the instant messaging session based upon remote detection of the user's return to the processor. A second instant messaging session can also be remotely activated on a second processor operated by another user_id by detecting the first user's approach to such second processor. The first user is automatically disengaged from this second instant messaging session when the user leaves the location of the second processor.

  • Integrated paper comprising fibrillated fibers and active particles immobilized therein
    Patent number: 7655112
    Abstract: An integrated paper having capabilities and functionalities provided by both the fiber and the active agent ingredients, and a method of immobilizing the active agents within the integrated paper. A tight pore structure with a mean pore diameter of less than about 2 microns provides short diffusion distances from a fluid to the surface of the paper ingredients by adsorption or diffusive interception, making it an excellent medium for fluid filtration. A microbiological interception enhancing agent may be added. The integrated paper may be formed using wet laid paper-making processes. Devices utilizing the integrated paper are used in fluid filtration.
