  • Patent number: 6923862
    Abstract: The invention provides a device for coating a conductor wire, the device comprising an enameling oven, the oven comprising a chamber through which the wire coated in an enameling varnish passes, and being provided for this purpose with a wire inlet and a wire outlet, and with means for heating the wire along its path within the chamber in order to evaporate solvent from the varnish and bake the varnish on the wire, the atmosphere inside the chamber having low oxygen content, the chamber further comprising a fan and an air feed inlet communicating with the chamber and servo-controlled to means for measuring the oxygen content. In the device, the fan and the air feed inlet are situated in distinct positions that are spaced apart from each other, the fan being situated between the solvent evaporation zone and the air feed inlet in such a manner as to entrain the solvent towards the air feed inlet so that the solvent is treated by combustion outside the zone in which the varnish is baked.

  • Patent number: 6915827
    Abstract: An offset measuring mechanism and method used in a bonding apparatus, in which the object plane of a position detection camera is set on a hypothetical bonding working plane, and the image of imaging elements within the imaging plane is projected onto a bonding working plane. Furthermore, the tip end of a bonding tool is aligned with the bonding working plane. The object plane of the offset measuring camera is set on the bonding working plane, and the image on the bonding working plane is projected onto the imaging elements of the imaging plane of the offset measuring camera. The imaging elements detect the projected image of the imaging elements of the position detection camera or the image of the tip end of the bonding tool and output this data to the image position measuring part or tool position measuring section of the control block.

  • Patent number: 6911091
    Abstract: Systems and methods are described for environmental exchange control for a polymer on a wafer surface. An apparatus for controlling an exchange between an environment and a polymer on a surface of a wafer located in the environment includes: a chamber adapted to hold the wafer, define the environment, and maintain the polymer in an adjacent relationship with the environment; and a heater coupled to the chamber. A method for improving performance of a spin-on material includes: forming the spin-on material on a surface of a wafer; then locating the spin-on material in an environment so that said environment is adjacent said spin-on material; and then controlling an exchange between the spin-on material and said environment. The systems and methods provide advantages because inappropriate deprotection is mitigated by careful control of the environmental temperature and environmental species partial pressures (e.g. relative humidity).

  • Patent number: 6911088
    Abstract: A slit nozzle includes a solution feeding mechanism having an elastic element and a plurality of piezoelectric devices and embedded in a side surface of a flow passage near a slit in the slit nozzle. Control is effected so that the piezoelectric devices are vibrated to cause the elastic element to produce traveling waves toward the slit. A resist solution serving as a processing solution is pumped by the traveling waves, thereby to be discharged through the slit toward a substrate. This provides a substrate processing apparatus capable of smoothly discharging the processing solution to accomplish high discharge accuracy.

  • Patent number: 6896022
    Abstract: A label affixer shoe, having an application blade with an edge, a first surface, and second surface, and a pivot. The shoe pivots between first and second orientations. The first surface, edge, said second surface separate a label from a liner when the label and liner are moved from the first surface of the shoe past the edge toward the second surface. The shoe may be incorporated into an affixer carriage, also including a pivot actuator. The shoe may be incorporated into an affixer module, with a translation actuator, a card feed mechanism, and a label feed mechanism. When the blade is in the first orientation, the shoe does not obstruct the feeding of the card to or from the label receiving position. The translation of the shoe from the first position to the second position while the blade is in the second orientation applies the label to the card.

  • Patent number: 6884462
    Abstract: A method and apparatus is provided for more efficient application of photoresist to a wafer surface. One aspect of the method comprises applying solvent to the wafer and spinning it to coat the entire wafer surface prior to the application of photoresist. This reduces surface tension on the wafer and reduces the amount of resist required to achieve a high quality film. The apparatus comprises adding a third solenoid and nozzle to the coating unit to accommodate the application of solvent to the center of the wafer surface. The method also describes incorporating a new solvent comprising diacetone alcohol, which is a low-pressure solvent, providing extended process latitudes and reduced material expenditures.

  • Patent number: 6881264
    Abstract: A process tool, preferably a spin coater, includes a set of at least three arms and an adjustable rinse nozzle. The arms lift a substrate, e.g. a semiconductor wafer, from a chuck inside the process chamber after having performed the corresponding manufacturing step, e.g. coating. The contact area between the arms and the substrate is as small as possible. The rinse nozzle dispenses a solvent liquid onto the backside of the substrate, thereby removing contaminating particles located at the area of contact between the vacuum channels of the chuck and the substrate. The set of arms rotates for a homogeneous cleaning. A gas flowing out of vacuum ports of the chuck prevents the vacuum ports from being obstructed with particles. While the substrate is being lifted, the chuck can also be cleaned by dispensing the solvent liquid onto the chuck.
