The present application is directed to interbody spinal fusion implants having a structural configuration that provides for the maintaining and creating of the normal anatomic angular relationship of two adjacent vertebrae of the spine to maintain and create spinal lordosis. The spinal fusion implants are sized to fit within the disc space created by the removal of disc material between two adjacent vertebrae and conform wholly or in part to the disc space created. The spinal fusion implants of the present invention have upper and lower surfaces that form a support structure for bearing against the end plates of the adjacent vertebrae. The upper and lower surfaces are disposed in a converging angular relationship to each other such that the implants have an overall “wedged-shape” in an elevational side view. The angular relationship of the upper and lower surfaces places and maintains the vertebrae adjacent to those surfaces in an angular relationship to each other, creating and maintaining the desired lordosis.

Superabrasive tools and methods for the making thereof are disclosed and described.

The present invention discloses a CMP pad dresser which has a plurality of uniformly spaced abrasive particles protruding therefrom. The abrasive particles are super hard materials, and are typically diamond, polycrystalline diamond (PCD), cubic boron nitride (cBN), or polycrystalline cubic boron nitride(PcBN). The abrasive particles are brazed to a substrate which may be then coated with an additional anti-corrosive layer. The anti-corrosive layer is usually a diamond or diamond-like carbon which is coated over the surface of the disk to prevent erosion of the brazing alloy by the chemical slurry used in conjunction with the CMP pad. This immunity to chemical attack allows the CMP pad dresser to dress the pad while it is polishing a workpiece. In addition to even spacing on the substrate, the abrasive particles extend for a uniform distance away from the substrate, allowing for even grooming or dressing of a CMP pad both in vertical and horizontal directions. A method of producing such a CMP pad dresser is also disclosed.

A liquid metal evaporation source for use in Molecular Beam Epitaxy and related metal vacuum deposition techniques. An evaporator is maintained at a high temperature to evaporate a liquid metal, a reservoir for holding the liquid metal source is maintained at a temperature above the melting point of the metal but below the temperature in the evaporator, and a hollow transport tube connecting the evaporator and reservoir is maintained at a temperature between these temperatures. The reservoir is in the shape of a hollow cylinder with a close-fitting cylindrical piston which is used to force the liquid metal through the hollow transport tube into the evaporator. The liquid metal will not flow past the piston seal if a suitably small gap is formed between the piston and the reservoir walls wherein the surface tension of the liquid metal will exceed its hydrostatic pressure against the piston thus forming a leak-tight seal.

Bump formation method and wire bonding method including a step of forming a ball on the tip end of a wire that passes through a capillary and joining this ball to an electrode pad so as to make a press-bonded ball. In the next step, the capillary is raised and moved horizontally so that the bottom flat portion of the capillary faces the press-bonded ball. Then, the capillary is lowered and the press-bonded ball is pressed, thus forming a first bump. Next, the capillary is raised and moved horizontally in a direction that is opposite from the previous horizontal-direction, thus positioning the flat portion of the capillary to face the first bump. Then, the capillary is lowered, and the wire is bent and pressed against the surface of the first bump so as to form a second bump. The wire is then cut from the second bump.
