  • Publication number: 20070155640
    Abstract: A method for making a solution for use in preparing a surface of a substrate is provided. The method includes providing a continuous medium that adds a polymer material to the continuous medium. A fatty acid is adding to the continuous medium having the polymer material, and the polymer material defines a physical network that exerts forces in the solution that overcome buoyancy forces experienced by the fatty acid, thus preventing the fatty acids from moving within the solution until a yield stress of the polymer material is exceeded by an applied agitation. The applied agitation is from transporting the solution from a container to a preparation station that applies the solution to the surface of the substrate.

    Abstract: A method and system for cleaning a surface, having particulate matter thereon, of a substrate features impinging upon the surface a jet of a liquid having coupling elements entrained therein. A sufficient drag force is imparted upon the coupling elements to have the same move with respect to the liquid and cause the particulate matter to move with respect to the substrate.

  • Publication number: 20070084483
    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.

  • Publication number: 20070084485
    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.

  • Publication number: 20070079848
    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: 7165563
    Abstract: An apparatus and a method is provided for decoupling a cavitation in a liquid from an acoustic energy used to induce the cavitation. Broadly speaking, a pressure adjustment is used to control an acoustically induced cavitation in a liquid contained within a wafer cleaning apparatus, wherein the cavitation is defined by an amount and a size of gas bubbles. An increase in a pressure within the wafer cleaning apparatus results in a suppression of the cavitation. Conversely, a decrease in the pressure within the wafer cleaning apparatus results in an enhancement of the cavitation. Thus, independent control of the cavitation is provided without regard to the acoustic energy or a chemistry of the liquid. Controlling the cavitation allows for a safe and efficient wafer cleaning operation that can be customized to address specific requirements dictated by a particular wafer configuration.

  • Publication number: 20070000518
    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.

    Abstract: In one embodiment, a substrate preparation system is provided. The system includes a brush, a front head, and a back head. The brush is configured to brush scrub a back surface of a substrate using a brush scrubbing chemistry. The front head is defined in close proximity to a front surface of the substrate while the back head is defined in close proximity to the back surface of the substrate. The back head is positioned substantially opposite to the front head. The front head and the back head are applied as a pair to the substrate when the brush is apart from the substrate.

  • Patent number: 7078344
    Abstract: A system and method for planarizing and controlling non-uniformity on a patterned semiconductor substrate includes receiving a patterned semiconductor substrate. The patterned semiconductor substrate having a conductive interconnect material filling multiple features in the pattern. The conductive interconnect material having an overburden portion. A bulk of the overburden portion is removed and a remaining portion of the overburden portion has a non-uniformity. The non-uniformity is mapped, optimal solution determined and a dynamic liquid meniscus etch process recipe is developed to correct the non-uniformity. A dynamic liquid meniscus etch process, using the dynamic liquid meniscus etch process recipe, is applied to correct the non-uniformity to substantially planarize the remaining portion of the overburden portion.

  • Patent number: 7067016
    Abstract: A method for post-etch cleaning of a substrate with MRAM structures and MJT structures and materials is disclosed. The method includes inserting the substrate into a first brush box configured for double-sided mechanical cleaning of the substrate. A non-HF, copper compatible chemistry is introduced into the first brush box for cleaning the active and backside surfaces of the substrate. The substrate is then inserted into a second brush box which is also configured to provide double-sided mechanical cleaning of the active and backside surfaces of the substrate. A burst of chemistry is introduced into the second brush box followed by a DIW rinse. The substrate is then processed through an SRD apparatus for final rinse and dry.
