  • Publication number: 20020197416
    Abstract: A gas jet deposition method and apparatus includes a plurality of ports to supply plasma to the substrate on which deposition is to occur. A reagent gas is introduced either into the ports or into the expansion chamber. The use of multiple ports results in a much more uniform deposition of material on the substrate. In preferred embodiments, a carrier gas plasma is created using an excitation source such as a microwave power supply.

  • Patent number: 6464025
    Abstract: A coast control device for a walkie/rider pallet truck locks the position of a steering arm of the truck to prevent movement by a deadman mechanism. The disclosed locking device is a brake: an armature plate mounted to the steering arm; and an electromagnet coupled to a steering head that is operated to activate coasting operation. The brake force can be overcome by an operator to manually apply the truck brake or to reposition the steering arm to a new position where it is again locked. For controlling coasting operation, the brake is manually engaged by an actuator mounted adjacent to or on a grab bar that is to be gripped by an operator riding on the truck. With the actuator so located, coasting operation can be conveniently engaged while the operator is walking beside the truck.

  • Publication number: 20020119657
    Abstract: The present invention provides a method for improving the adhesion of copper and other metal-comprising conductive metals to a barrier layer. A barrier is provided that has a first surface that is substantially unoxidized, wherein at least a portion of the surface is free from the presence of oxygen atoms. A conductive layer is then deposited onto the first surface of the barrier layer. The substantially unoxidized state of the first surface enhances the adhesion of the metal-comprising layer to the barrier layer. The method is particularly useful in obtaining excellent adhesion of a copper nucleation layer to an underlying barrier layer surface.

  • Publication number: 20020058408
    Abstract: The present invention provides a method and apparatus for forming reliable interconnects in which the overlap of the line over the plug or via is minimized or eliminated. In one aspect, a barrier plug comprised of a conductive material, such as tungsten, is deposited over the via to provide an etch stop during line etching and to prevent diffusion of the metal, such as copper, into the surrounding dielectric material if the line is misaligned over the via. Additionally, the barrier plug prevents an overall reduction in resistance of the interconnect and enables reactive ion etching to be employed to form the metal line. In another aspect, reactive ion etching techniques are employed to selectively etch the metal line and the barrier layer to provide a controlled etching process which exhibits selectivity for the metal line, then the barrier and then the via or plug.

  • Publication number: 20010033890
    Abstract: The neuro-cottonoid dispensing device comprises a tray of plastic or similar disposable material with a trough and a series of channels to accommodate neurosurgical sponges. A neurosurgical sponge comprises a string attached to an absorbent material, usually cotton. Either the sponge or the string can be radio-opaque (x-ray detectable). The absorbent part of the neurosurgical sponge is often referred to as a cottonoid by those skilled in the art. The aforementioned grooves or channels keep the strings tangle-free and the cottonoids immediately accessible. The cottonoids rest within the trough. Immediately preceding or during neurosurgery, the trough can be filled with a wetting solution, usually saline. A plastic film or similar material covers the tray and encloses the neurosurgical sponges in a sterile environment.

  • Patent number: 5672537
    Abstract: Polysilicon (20) in a trench (21) is etched at an angle to produce a conductor within the trench that has shape characteristics which approximate the shadow of the side wall (26) of the trench (21) closest the beam source. Specifically, when the first side wall (26) is closest the beam source and the second side wall (27) is furthest from the beam source, the polysilicon on the first side wall (26) is almost as high as the first side wall (26), while the polysilicon on the more exposed side wall (27) is considerably lower than the first side wall (26) and approximates the shadow of the first side wall (26) on the second side wall (27) relative to the beam.
