  • Publication number: 20240289000
    Abstract: Various aspects and embodiments are directed to a graphical user interface that organizes interface elements into views of computer content for presentation to a user. Different views of are used to provide an interface that is responsive to configurations of the device and activities performed by the user. Aspects include permitting the user to transition the device from one configuration to another during its use. The elements that comprise the graphical user interface are configured to present a summarized view of available actions and content to simplify user interaction. The different views present different organizations of the interface elements and in some examples display only certain modes of content in order to reduce the number of options a user must navigate. Methods and systems for streamlining user interaction with computer content are also provided. Streamlining includes, for example, pre-configuring a user device based on received information.

  • Patent number: 7667835
    Abstract: An apparatus and method for preventing the peeling of electroplated metal from a wafer, is disclosed. The apparatus includes a seed layer detector system having a light source and a reflectivity detector. According to the method, the light source emits a beam of light onto a wafer and the reflectivity detector receives the light reflected from the wafer. The reflectivity of the wafer surface is measured to determine the presence or absence of a seed layer on the wafer, as well as whether the seed layer has a minimum thickness for optimum electroplating of a metal onto the seed layer.

  • Patent number: 7432192
    Abstract: A method of forming a copper interconnect in a dual damascene scheme is described. After a diffusion barrier layer and seed layer are sequentially formed on the sidewalls and bottoms of a trench and via in a dielectric layer, a first copper layer is deposited by a first ECP process at a 10 mA/cm2 current density to fill the via and part of the trench. A first anneal step is performed to remove carbon impurities and optionally includes a H2 plasma treatment. A second ECP process with a first deposition step at a 40 mA/cm2 current density and second deposition step at a 60 mA/cm2 current density is used to deposit a second copper layer that overfills the trench. After a second anneal step, a CMP process planarizes the copper layers. Fewer copper defects, reduced S, Cl, and C impurities, and improved Rc performance are achieved by this method.

  • Publication number: 20080067076
    Abstract: A novel method, which is suitable to substantially reduce the presence of oxygen micro-bubbles in an electroplating bath solution, is disclosed. The method includes the addition of aerobic bacteria to the electroplating bath solution to consume oxygen in the solution. Reduction of the oxygen content in the electroplating bath solution prevents oxygen micro-bubbles from forming in the solution and becoming trapped between the solution and the surface of a metal seed layer on a substrate to block the electroplating of a metal film onto the seed layer. Consequently, the presence of surface pits and other structural defects in the surface of the electroplated metal film is substantially reduced.

  • Patent number: 7208404
    Abstract: A method of forming a copper interconnect in an opening within a pattern is described. The copper interconnect has an Rs that is nearly independent of opening width and pattern density. A first copper layer having a concave upper surface and thickness t1 is formed in a via or trench in a dielectric layer by depositing copper and performing a first CMP step. A second copper layer with a thickness t2 where t2?t1 and having a convex lower surface is deposited on the first copper layer by a selective electroplating method. The first and second copper layers are annealed and then a second CMP step planarizes the second copper layer to become coplanar with the dielectric layer. The invention is also a copper interconnect comprised of the aforementioned copper layers where the first copper layer has a grain density (GD1)?GD2 for the second copper layer.

  • Patent number: 7183199
    Abstract: A method of reducing the pattern effect in the CMP process. The method comprises the steps of providing a semiconductor substrate having a patterned dielectric layer, a barrier layer on the patterned dielectric layer, and a conductive layer on the barrier layer; performing a first CMP process to remove part of the conductive layer before the barrier layer is polished, thereby a step height of the conductive layer is reduced; depositing a layer of material substantially the same as the conductive layer on the conductive layer; and performing a second CMP process to expose the dielectric layer. A method of eliminating the dishing phenomena after a CMP process and a CMP rework method are also provided.

  • Publication number: 20060213778
    Abstract: A method of electroplating conductive material on semiconductor wafers improves deposited film quality by providing greater control over the formation of the film grain structure. Better grain size control is achieved by applying a continuous DC plating current to the wafer which avoids sharp discontinuities in the current as the applied current is increased in successive stages during a plating cycle. Current discontinuities are avoided by gradually increasing the current in a ramp-like fashion between the successive plating stages.

  • Publication number: 20050121329
    Abstract: A thrust pad assembly which is capable of reducing the quantity of metal electroplated onto the edge region of a substrate to eliminate or reduce the need for edge bevel cleaning or removal of excess metal from the substrate after the electroplating process. The thrust pad assembly includes an air platen through which air is applied at variable pressures to the central and edge regions, respectively, of a thrust pad. The thrust pad applies pressure to a contact ring connected to an electroplating voltage source. The contact ring applies relatively less pressure to the edge region than to the central region of the substrate, thereby reducing the ohmic contact.
