  • Publication number: 20130284217
    Abstract: A substrate cleaning systems are provided. One system includes a proximity head system for applying a meniscus to a surface of a substrate during a cleaning operation. Also provided is a container for holding the solution, the solution being mixed from at least a continuous medium, a polymer material, and a solid material, the polymer material in the solution imparting a finite yield stress to the material, such that the solution is maintained in a stable elastic gel form. A pump coupled to the container is also provided for moving the solution from the container to the proximity head system, where the pump applies at least a minimum shear stress on the solution. The pump provides agitation that exceeds the finite yield stress causing the solution to flow. A conduit is provided between the container and the proximity head system.

  • Patent number: 8555903
    Abstract: A cleaning material is disposed over a substrate. The cleaning material includes solid components dispersed within a liquid medium. A force is applied to the solid components within the liquid medium to bring the solid components within proximity to contaminants present on the substrate. The force applied to the solid components can be exerted by an immiscible component within the liquid medium. When the solid components are brought within sufficient proximity to the contaminants, an interaction is established between the solid components and the contaminants. Then, the solid components are moved away from the substrate such that the contaminants having interacted with the solid components are removed from the substrate.

  • Patent number: 8522801
    Abstract: A method for cleaning a substrate is provided. The method initiates with disposing a fluid layer having solid components therein to a surface of the substrate. A shear force directed substantially parallel to the surface of the substrate and toward an outer edge of the substrate is then created. The shear force may result from a normal or tangential component of a force applied to a solid body in contact with the fluid layer in one embodiment. The surface of the substrate is rinsed to remove the fluid layer. A cleaning system and apparatus are also provided.

  • Patent number: 8490573
    Abstract: Broadly speaking, a method and an apparatus are provided for depositing a material on a semiconductor wafer (“wafer”). More specifically, the method and apparatus provide for selective heating of a surface of the wafer exposed to an electroless plating solution. The selective heating is provided by applying radiant energy to the wafer surface. The selective heating of the wafer surface causes a temperature increase at an interface between the wafer surface and the electroless plating solution. The temperature increase at the interface in turn causes a plating reaction to occur at the wafer surface. Thus, material is deposited on the wafer surface through an electroless plating reaction that is initiated and controlled by varying the temperature of the wafer surface using an appropriately defined radiant energy source.

  • Patent number: 8419917
    Abstract: An electroplating head is disposed above and proximate to an upper surface of a wafer. Cations are transferred from an anode to an electroplating solution within the electroplating head. The electroplating solution flows downward through a porous electrically resistive material at an exit of the electroplating head to be disposed on the upper surface of the wafer. An electric current is established between the anode and the upper surface of the wafer through the electroplating solution. The electric current is uniformly distributed by the porous electrically resistive material present between the anode and the upper surface of the wafer. The electric current causes the cations to be attracted to the upper surface of the wafer.

  • Patent number: 8048283
    Abstract: First and second electrodes are disposed at first and second locations, respectively, proximate to a periphery of a wafer support, wherein the first and second location are substantially opposed to each other relative to the wafer support. Each of the first and second electrodes can be moved to electrically connect with and disconnect from a wafer held by the wafer support. An anode is disposed over and proximate to the wafer such that a meniscus of electroplating solution is maintained between the anode and the wafer. As the anode moves over the wafer from the first location to the second location, an electric current is applied through the meniscus between the anode and the wafer. Also, as the anode is moved over the wafer, the first and second electrodes are controlled to connect with the wafer while ensuring that the anode does not pass over an electrode that is connected.
