  • Patent number: 10700072
    Abstract: Memory devices and methods of forming memory devices are described. The memory devices comprise a substrate with at least one film stack. The film stack comprises a polysilicon layer on the substrate; a bit line metal layer on the polysilicon layer; a cap layer on the bit line metal layer; and a hardmask on the cap layer. The memory device of some embodiments includes an optional barrier metal layer on the polysilicon layer and the bit line metal layer is on the barrier metal layer. Methods of forming electronic devices are described where one or more patterns are transferred through the films of the film stack to provide the bit line of a memory device.

  • Patent number: 10304732
    Abstract: Methods and apparatus for filling features with cobalt are provided herein. In some embodiments, a method for processing a substrate includes: depositing a first cobalt layer via a chemical vapor deposition (CVD) process atop a substrate and within a feature disposed in the substrate; and at least partially filling the feature with cobalt or cobalt containing material by performing a plasma process in a physical vapor deposition (PVD) chamber having a cobalt target to reflow a portion of the first cobalt layer into the feature. The PVD chamber may be configured to simultaneously deposit cobalt or cobalt containing material within the feature from a cobalt target disposed in the PVD chamber.

  • Publication number: 20180323103
    Abstract: Embodiments of methods and apparatus for filling a feature disposed in a substrate are disclosed herein. In some embodiments, a method for filling a feature disposed in a substrate includes (a) depositing a metal within the feature to a first predetermined thickness in a first process chamber; (b) depositing the metal within the feature to a second predetermined thickness in a second process chamber; (c) etching the metal deposited in (b) to remove an overhang of the metal at a top of the feature in a third process chamber different than the first and second process chambers; and (d) subsequent to (c), filling the feature with the metal in a fourth process chamber different than the first and third process chambers.

  • Publication number: 20170145553
    Abstract: Implementations of the present disclosure relate to an improved shield for use in a processing chamber. In one implementation, the shield includes a hollow body having a cylindrical shape that is substantially symmetric about a central axis of the body, and a coating layer formed on an inner surface of the body. The coating layer is formed the same material as a sputtering target used in the processing chamber. The shield advantageously reduces particle contamination in films deposited using RF-PVD by reducing arcing between the shield and the sputtering target. Arcing is reduced by the presence of a coating layer on the interior surfaces of the shield.

  • Publication number: 20160055272
    Abstract: A method for generating a testbench for an IC is provided. Design information of the IC is obtained according to a bus configuration. The design information is displayed in a graphical user interface (GUI). The design information is modified according to a first user input. It is determined whether the modified design information is correct according to a register transfer level (RTL) code of the IC. The testbench for the IC is generated according to the modified design information when the modified design information is correct.

  • Publication number: 20120052679
    Abstract: A method of providing a metal contact to n-type Gallium Nitride is disclosed. The method does not require high temperatures that often lead to a degradation of semiconductor materials, dielectric films, interfaces and/or metal-semiconductor junctions. The method can be applied at practically any step of a semiconductor device fabrication process and results in high quality ohmic contact with low contact resistance and high current handling capability. Present invention significantly simplifies the fabrication process of semiconductor devices, such as Gallium Nitride-based Light Emitting Diodes and Laser Diodes, while improving the resulting performance of the said devices. The invention can also be applied to improve the performance of electronic devices based on Gallium Nitride material system, especially where an additional annealing step is beneficial during the fabrication process.

  • Patent number: 8099702
    Abstract: Various methods and apparatuses (such as computer readable media implementing the method) are described that relate to proximate placement of sequential cells of an integrated circuit netlist. For example, the preliminary placement is received; and based on the preliminary placement, a group of sequential cells is identified as being subject to improved power and/or timing upon subsequent placement. In another example, identification is received of a group of sequential cells subject to improved power and/or timing upon subsequent placement; and proximate placement is performed of the identified group of sequential cells. In yet another example, a proximate arrangement of a group of sequential cells is received; and if proximate placement fails, then the group of sequential cells is disbanded and placement is performed of the sequential cells of the disbanded group.
