  • Publication number: 20130048021
    Abstract: A method for cleaning a substrate is provided. The method initiates with applying an activation solution to a surface of the substrate. The activation solution and the surface of the substrate are contacted with a surface of a solid cleaning surface. The activation solution is absorbed into a portion of the solid cleaning element and then the substrate or the solid cleaning surface is moved relative to each other to clean the surface of the substrate. A method for cleaning the surface of the substrate with a solid cleaning element that experiences plastic deformation is also provided. Corresponding cleaning apparatuses are also provided.

  • Patent number: 8323420
    Abstract: A pressure is maintained within a volume within which a semiconductor wafer resides at a pressure that is sufficient to maintain a liquid state of a precursor fluid to a non-Newtonian fluid. The precursor fluid is disposed proximate to a material to be removed from the semiconductor wafer while maintaining the precursor fluid in the liquid state. The pressure is reduced in the volume within which the semiconductor wafer resides such that the precursor fluid disposed on the wafer within the volume is transformed into the non-Newtonian fluid. An expansion of the precursor fluid and movement of the precursor fluid relative to the wafer during transformation into the non-Newtonian fluid causes the resulting non-Newtonian fluid to remove the material from the semiconductor wafer.

  • Patent number: 8011116
    Abstract: A method is provided for removing a residual fluid remaining at a point of contact between a substrate support member and a back surface of a substrate being prepared by a proximity head. According to the method, the proximity head is applied onto the back surface of the substrate and the substrate support member being held by a carrier. The substrate support member is heated after the substrate support member passes the proximity head. The heating of the substrate support member is discontinued once the residual fluid has substantially evaporated.

    Abstract: Material for cleaning using a tri-state body are disclosed. A substrate having a particle deposited thereon is provided. A tri-state body that has a solid portion, liquid portion, and a gas portion is generated. A force is applied over the tri-state body to promulgate an interaction between the solid portion and the particle. The tri-state body is removed along with the particle from the surface of the substrate. The interaction between the solid portion and the particle causes the particle to be removed along with the tri-state body.

  • Publication number: 20100206340
    Abstract: A method is provided for removing contamination from a substrate. The method includes applying a cleaning solution having a dispersed phase, a continuous phase and particles dispersed within the continuous phase to a surface of the substrate. The method includes forcing one of the particles dispersed within the continuous phase proximate to one of the surface contaminants. The forcing is sufficient to overcome any repulsive forces between the particles and the surface contaminants so that the one of the particles and the one of the surface contaminants are engaged. The method also includes removing the engaged particle and surface contaminant from the surface of the substrate. A process to manufacture the cleaning material is also provided.

  • Publication number: 20100059088
    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: 7648616
    Abstract: A number of apertures are defined within a wall of a chamber defined to maintain an electrolyte solution. A cation exchange membrane is disposed within the chamber over the number of apertures. The electrolyte solution pressure within the chamber causes the cation exchange membrane to extend through the apertures beyond an outer surface of the chamber. A cathode is disposed within the chamber. The cathode is maintained at a negative bias voltage relative to a top surface of a wafer to be planarized. When the top surface of the wafer is brought into proximity of the cation exchange membrane extending through the apertures, and a deionized water layer is disposed between the top surface of the wafer and the cation exchange membrane, a cathode half-cell is established such that metal cations are liberated from the top surface of the wafer and plated on the cathode in the chamber.
