  • Publication number: 20120181180
    Abstract: Some embodiments of the present invention provide processes and apparatus for electrochemically fabricating multilayer structures (e.g. mesoscale or microscale structures) with improved endpoint detection and parallelism maintenance for materials (e.g. layers) that are planarized during the electrochemical fabrication process. Some methods involve the use of a fixture during planarization that ensures that planarized planes of material are parallel to other deposited planes within a given tolerance. Some methods involve the use of an endpoint detection fixture that ensures precise heights of deposited materials relative to an initial surface of a substrate, relative to a first deposited layer, or relative to some other layer formed during the fabrication process. In some embodiments planarization may occur via lapping while other embodiments may use a diamond fly cutting machine.

One method includes providing a plating assembly having a plating source in a plating fluid and a plating facilitator in the plating fluid, and defining a plating meniscus between the plating source and the plating facilitator. The plating meniscus being contained in a path of the plating assembly. The method further includes traversing a substrate through the path of the plating assembly. The substrate being charged so that plating ions are attracted to a surface of the substrate when the plating meniscus is present on the surface of the substrate, wherein the substrate traversing through the path of the plating assembly enables plating across the surface of the substrate. And, inducing a uniform charge in the path where the plating meniscus is formed, such that charge from the plating source is substantially uniformly directed toward the plating facilitator as the substrate that is charged moves through the path of the plating assembly.

  • Patent number: 8197662
    Abstract: The present invention provides improved methods and devices for electroplating copper on a wafer. Some implementations of the present invention involve the pre-treatment of the wafer with a solution containing accelerator molecules. Preferably, the bath into which the wafer is subsequently placed for electroplating has a reduced concentration of accelerator molecules. The pre-treatment causes a reduction in roughness of the electroplated copper surface, particularly during the initial phases of copper growth.

  • Publication number: 20120132529
    Abstract: The present invention is related to a method for masked anodization of an anodizable layer on a substrate, for example an aluminum layer present on a sacrificial layer, wherein the sacrificial layer needs to be removed from a cavity comprising a Micro or Nano Electromechanical System (MEMS or NEMS). Anodization of an Al layer leads to the formation of elongate pores, through which the sacrificial layer can be removed. According to the method of the invention, the anodization of the Al layer is done with the help of a first mask which defines the area to be anodized, and a second mask which defines a second area to be anodized, said second area surrounding the first area. Anodization of the areas defined by the first and second mask leads to the formation of an anodized structure in the form of a closed ring around the first area, which forms a barrier against unwanted lateral anodization in the first area.

    Abstract: Disclosed is an electrochemical etching system with localized etching capability. The system allows multiple different porous semiconductor regions to be formed on a single semiconductor wafer. Localized etching is achieved through the use of one or more stationary and/or movable computer-controlled inner containers operating within an outer container. The outer container holds the electrolyte solution and acts as an electrolyte supply source for the inner container(s). The inner container(s) limit the size of the etched region of the semiconductor wafer by confining the electric field. Additionally, the current amount passing through each inner container during the electrochemical etching process can be selectively adjusted to achieve a desired result within the etched region. Localized etching of sub-regions within each etched region can also be achieved through the use of different stationary and/or moveable electrode structures and shields within each inner container.

  • Patent number: 8021535
    Abstract: Methods and structures for electroplating shield structures for perpendicular thin film write poles having ultra thin non-magnetic top gaps on the order of a few nanometers are disclosed. Ultra thin, conductive seed layers serve a dual purpose as both plating seed layer and non-magnetic top gap for the write pole. Due to reduced current carrying capacity of ultra thin seed layers, an additional thick seed layer is also employed to aid delivering plating current to regions near the pole.

  • Publication number: 20110212313
    Abstract: Metal nanoparticles are assembled in interrupted metal strands or other structures of characteristic dimensions and orientation to generate a giant dielectric response through a modified GE effect. Careful selection and modification of the host material and synthesis also leads to low dielectric breakdown voltages. In addition, the high dielectric composite material is employed in material configurations that are more scalable for industrial and consumer applications.

  • Publication number: 20110203936
    Abstract: A method of forming three-dimensional structures includes forming a conductive layer on a substrate and patterning a resist layer over the conductive layer, the resist layer having contained therein a plurality of vias. An electrically conductive polymer is then electro-deposited in the vias. The electro-deposition operation is then stopped to form one or more of posts, posts having bulbous termini (i.e., mushrooms), or a layer atop the resist layer. The resist may be removed to yield the structure which may be further processed. For example, the structure may be pyrolyzed. In addition, biomolecules may also be adhered or otherwise affixed to the structure.

  • Publication number: 20110180412
    Abstract: A plating method can fill a plated metal into interconnect recesses at a higher rate without forming voids in the plated metal embedded in the interconnect recesses. The plating method includes: preparing a substrate having interconnect recesses in a surface; carrying out first pretreatment of the substrate by immersing the substrate in a first pretreatment solution containing an accelerator, a metal ion and an acid; carrying out second pretreatment of the substrate by immersing the substrate in a second pretreatment solution containing an additive which inhibits the effect of the accelerator contained in the first pretreatment solution, and not containing an accelerator; and then carrying out electroplating of the substrate surface by using a plating solution containing at least a metal ion, an acid and a suppressor, and not containing an accelerator, thereby filling the plated metal into the interconnect recesses.

  • Publication number: 20110168669
    Abstract: Disclosed herein is a method of preparing a low resistance metal line, in which a wet plating technique is used instead of a vacuum film forming process in order to simplify the process and decrease the manufacturing cost. In addition, a self-assembled monolayer is formed that facilitates the increased adsorption density and strength of the metal catalyst resulting in the formation of a high-density metal catalyst layer, thereby obtaining a high-quality metal line. Also disclosed herein, are a patterned metal line structure, and a display device using the same.

  • Publication number: 20110155580
    Abstract: Multi-layer microscale or mesoscale structures are fabricated with adhered layers (e.g. layers that are bonded together upon deposition of successive layers to previous layers) and are then subjected to a heat treatment operation that enhances the interlayer adhesion significantly. The heat treatment operation is believed to result in diffusion of material across the layer boundaries and associated enhancement in adhesion (i.e. diffusion bonding). Interlayer adhesion and maybe intra-layer cohesion may be enhanced by heat treating in the presence of a reducing atmosphere that may help remove weaker oxides from surfaces or even from internal portions of layers.
