  • Publication number: 20110065621
    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.

  • Patent number: 7875554
    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: 7862693
    Abstract: An electroplating apparatus for electroplating a surface of a wafer is provided. The wafer is capable of being electrically charged as a cathode. The electroplating apparatus includes a plating head capable of being positioned either over or under the surface of a wafer and capable of being electrically charged as an anode. The plating head is capable of enabling metallic plating between the surface of the wafer and the plating head when the wafer and plating head are charged. The plating head further comprises a voltage sensor pair capable of sensing a voltage present between the plating head and the surface of the wafer, and a controller capable of receiving data from the voltage sensor pair. The data received from the voltage sensor pair is used by the controller to maintain a substantially constant voltage to be applied by the anode when the plating head is placed in positions over the surface of the wafer. A method of electroplating a wafer is also provided.

  • 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: 20100170803
    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.

  • 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: 7604011
    Abstract: An apparatus and a method is provided for using high-frequency acoustic energy with a supercritical fluid to perform a semiconductor wafer (“wafer”) cleaning process. High-frequency acoustic energy is applied to the supercritical fluid to impart energy to particulate contamination present on the wafer surface. Energy imparted to particulate contamination via the high-frequency acoustic energy and supercritical fluid is used to dislodge and remove the particulate contamination from the wafer. Additionally, the wafer cleaning process benefits from the supercritical fluid properties of near zero surface tension, high diffusivity, high density, and chemical mixing capability.
