  • Publication number: 20050200024
    Abstract: The invention provides a method of forming a wiring layer in an integrated circuit structure that forms an organic insulator, patterns the insulator, deposits a liner on the insulator, and exposes the structure to a plasma to form pores in the insulator in regions next to the liner. The liner is formed thin enough to allow the plasma to pass through the liner and form the pores in the insulator. During the plasma processing, the plasma passes through the liner without affecting the liner. After the plasma processing, additional liner material may be deposited. After this, a conductor is deposited and excess of portions of the conductor are removed from the structure such that the conductor only remains within patterned portions of the insulator. This method produces an integrated circuit structure that has an organic insulator having patterned features, a liner lining the patterned features, and a conductor filling the patterned features.

  • Patent number: 6942291
    Abstract: A bicycle saddle includes a rigid/semi-rigid shell functioning as a supporting structure for the bicycle saddle. A covering is disposed on the shell and attached thereto, with a padding between the shell and the covering. The padding comprise a cushion made of a resilient material. The cushion includes a plurality of cavities and is attached to the top of the shell such that the cavities would work as pneumatic cushions with air cushions/air springs interposing between the shell and the rider's body.

  • Patent number: 6942601
    Abstract: A wrist exercise includes a casing defining an interior space rotatably receiving a rotor. The casing includes upper and lower casing members. The upper casing member has a first mating edge forming a first mating device. The lower casing member has a second mating edge forming a second mating device for mating the first mating device to attach the lower casing member to the upper casing member whereby a circumferential groove is defined between the first and second mating edges. A first retention ring is at least partially fit over the upper and lower casing members and forms an inwardly-projecting portion fit into the groove to securely retain the upper and lower casing members in position.

  • Patent number: 6921711
    Abstract: A structure and method for a metal replacement gate of a high performance device is provided. A sacrificial gate structure is first formed on an etch stop layer provided on a semiconductor substrate. A pair of spacers is provided on sidewalls of the sacrificial gate structure. The sacrificial gate structure is then removed, forming an opening. Subsequently, a metal gate including an first layer of metal such as tungsten, a diffusion barrier such as titanium nitride, and a second layer of metal such as tungsten is formed in the opening between the spacers.

  • Patent number: 6914320
    Abstract: An advanced back-end-of-line (BEOL) metallization structure is disclosed. The structure includes a bilayer diffusion barrier or cap, where the first cap layer is formed of a dielectric material preferably deposited by a high density plasma chemical vapor deposition (HDP CVD) process, and the second cap layer is formed of a dielectric material preferably deposited by a plasma-enhanced chemical vapor deposition (PE CVD) process. A method for forming the BEOL metallization structure is also disclosed. The invention is particularly useful in interconnect structure comprising low-k dielectric material for the inter-layer dielectric (ILD) and copper for the conductors.

The shock-absorbing member is made of non plastic composite materials having a hardness lower than that of the body. The shock-absorbing member is filled up the at least one opening of the body to form shock-absorbing zones of the bicycle saddle.

  • Publication number: 20050112864
    Abstract: An interconnect structure in the back end of the line of an integrated circuit forms contacts between successive layers by removing material in the top surface of the lower interconnect in a cone-shaped aperture, the removal process extending through the liner of the upper aperture, and depositing a second liner extending down into the cone-shaped aperture, thereby increasing the mechanical strength of the contact, which then enhance the overall reliability of the integrated circuit.

  • Patent number: 6884641
    Abstract: This invention relates to a method for electrically localizing site-specific defective sub 130 nm node MOSFET devices with shallow (less than 80 nm deep) source/drain junctions utilizing bulk silicon, or Silicon on Insulator (SOI), or strained silicon (SE), followed by optimized sample preparation steps that permits imaging, preferably high resolution electron holographic imaging, in an electron microscope to detect blocked implants, asymmetric doping, or channel length variations affecting MOSFET device performance. Detection of such defects in such shallow junctions enables further refinements in process simulation models and permits optimization of MOSFET device designs.

  • Patent number: 6878624
    Abstract: The present invention provides a method for forming an interconnect to a cobalt or nickel silicide having a TiN diffusion barrier. The inventive method comprises providing an initial structure having vias to exposed silicide regions positioned on a substrate; annealing the initial structure in a nitrogen-containing ambient, wherein a nitrogen passivation layer is formed atop the exposed silicide region; depositing Ti atop the nitrogen passivation layer; annealing the Ti in a nitrogen-containing ambient to form a TiN diffusion barrier and an amorphous Ti cobalt silicide between the TiN diffusion layer and the cobalt or nickel silicide and depositing an interconnect metal within the vias and atop the TiN diffusion barrier. The nitrogen passivation layer substantially restricts diffusion between the Ti and silicide layers minimizing the amorphous Ti cobalt silicide layer that forms. Therefore, the amorphous Ti cobalt or Ti nickel silicide is restricted to a thickness of less than about 3.0 nm.

  • Publication number: 20050067745
    Abstract: Disclosed is a method and structure for forming a silicide on a silicon material. The invention places the silicon material in a vacuum environment, forms metal on the silicon material, and then heats the silicon surface and the metal without breaking the vacuum environment. The processes of forming the metal and heating the silicon can be performed simultaneously without breaking the vacuum environment to form the silicide as the metal is being deposited. After the foregoing processing, the invention can remove the silicon surface from the vacuum environment and perform additional heating of the silicon surface. The first heating process forms a monosilicide and the additional heating forms a disilicide.
