  • Publication number: 20120010240
    Abstract: A cut-point in the quantitative measurement of PTEN protein expression that accurately identifies tumors with two inactivated alleles of the PTEN gene. Patients with a normalized PTEN score of PTEN null will be treated with a pan-ErbB tyrosine kinase inhibitor. A normalized PTEN protein expression score is obtained by comparing the tumor PTEN OD expression value with the non-malignant PTEN OD expression value.

  • Patent number: 8056604
    Abstract: A test casting is useful for predicting the severity of skin that will form when compacted graphite iron or ductile iron is cast using a selected foundry mix. The mold is made from the foundry mix and has a gating system with at least two ingates, and with a hollow cylindrical shape associated with each ingate. The hollow cylindrical shapes are substantially the same height, but the diameter of each varies by at least 20% from the diameter of any of the other cylindrical shapes. Molten metal poured into the gating system fills each of the hollow cylindrical shapes. When the metal cools and solidifies, a solid cylinder of the metal is produced in each hollow cylindrical shape. The solid metal cylinders, each with a distinct diameter, are cut and inspected to measure the skin formed thereon.

  • Publication number: 20070298608
    Abstract: Noble metal may be used as a non-oxidizing diffusion barrier to prevent diffusion from copper lines. A diffusion barrier may be formed of a noble metal formed over an adhesion promoting layer or by a noble metal cap over an oxidizable diffusion barrier. The copper lines may also be covered with a noble metal.

  • Patent number: 7220671
    Abstract: Chemical phase deposition processes utilizing organometallic precursors to form thin films are herein described. The organometallic precursors may include a single metal center or multiple metal centers. The chemical phase deposition may be chemical vapor deposition (CVD), atomic layer deposition (ALD), or hybrid CVD and ALD. The use of these chemical phase deposition processes with the organometallic precursors allows for the conformal deposition of films within openings having widths of less than 100 nm and more particularly less than 50 nm to form thin films such as barrier layers, seed layers, and adhesion layers.

  • Publication number: 20070075427
    Abstract: A method for forming a metal carbide layer begins with providing a substrate, an organometallic precursor material, at least one doping agent such as nitrogen, and a plasma such as a hydrogen plasma. The substrate is placed within a reaction chamber; and heated. A process cycle is then performed, where the process cycle includes pulsing the organometallic precursor material into the reaction chamber, pulsing the doping agent into the reaction chamber, and pulsing the plasma into the reaction chamber, such that the organometallic precursor material, the doping agent, and the plasma react at the surface of the substrate to form a metal carbide layer. The process cycles can be repeated and varied to form a graded metal carbide layer.

  • Publication number: 20060131276
    Abstract: A method for performing a batch spray comprises providing a substrate mounted upon a turntable, rotating the turntable to revolve the substrate around a center axis of the turntable, rotating the substrate independently of the turntable, wherein the rotating of the substrate occurs simultaneously with the rotating of the turntable, and spraying a chemical onto the substrate from at least one fixed location. Rotating the substrate independently of the turntable allows the entire circumference of the substrate to be exposed to the chemical spray. In one implementation, the substrate may be loaded into a process cassette, the process cassette may be mounted on the turntable, and the process cassette may rotate independently of the turntable while the turntable is rotating.

  • Publication number: 20060118968
    Abstract: Apparatus and methods of fabricating a microelectronic interconnect having an underlayer which acts as both a barrier layer and a seed layer. The underlayer is formed by co-depositing a noble metal and a barrier material, such as a refractory metal, or formed during thermal post-treatment, such as thermal annealing, conducted after two separately depositing the noble metal and the barrier material, which are substantially soluble in one another. The use of a barrier material within the underlayer prevents the electromigration of the interconnect conductive material and the use of noble material within the underlayer allows for the direct plating of the interconnect conductive material.
