  • Patent number: 8702956
    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.

  • Patent number: 8641883
    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.

  • Patent number: 8500968
    Abstract: An electroplating apparatus having improved contact deplating features includes a bowl assembly having a bowl for holding an electroplating solution. A head having a rotor including a contact ring and a head motor for rotating the rotor cooperates with the bowl assembly during plating operations. A lift/rotate actuator may be used to move the head to position a sector of the contact ring in a ring slot or opening of a deplating module. Since the deplating is performed within the deplating module, and not within the bowl assembly, the electroplating solution in the bowl assembly is not affected by the deplating process.

  • 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.
