20080204966 | Controlled Transport and Assembly of Nanostructures - Systems and methods for manipulating nanostructures, such as nanospheres, nanodisks, nanowires, and nanotubes. The systems and methods permit the construction of nano-scale contacts, scaffolds, and motors using electric fields that do not require the use of toxic nanostructure materials. The electric fields are imposed on the nanostructures using electrodes having specific shapes and driven with voltages having particular amplitudes, frequencies, and phase differences. The electrode shape and voltage characteristics influence the configuration of the electric fields, which in turn influences the ultimate configuration of the nanostructures. The nanostructures retain their configuration after the electric fields and any transport medium, such as deionized water, are removed. | 08-28-2008 |

20090147431 | ASSEMBLING STACKED SUBSTRATES THAT CAN FORM CYLINDRICAL INDUCTORS AND ADJUSTABLE TRANSFORMERS - A system is described that can assemble substrates over one another to form a stacked substrate. The various layers of the stacked substrate can be separated from each other by using Coulomb forces. In addition, a beam substrate can be used to increase the separation. The instructions for assembly and a FSM (Finite State Machine) can be included in the stacked substrate to pave the way for a self-constructing 3-D automaton. The beam substrate can be used to carry heat, fluids, electrical power or signals between the various layers of the stacked cells besides providing a mechanical support. A stacked substrate can be assembled into a cylindrical coil, a transformer or a coupled transformer depending on the construction of the beam structure. The magnetic coupling of the transformer can be altered by changing the distance between the separated substrates. | 06-11-2009 |
20090147432 | FORMING LARGE PLANAR STRUCTURES FROM SUBSTRATES USING EDGE COULOMB FORCES - A movable substrate is placed over a bottom substrate where both substrates contain Coulomb islands. The Coulomb islands can be adjusted in charge and are used to develop a force between two opposing Coulomb islands. Information from sensors is applied to a control unit to control the movement of the movable substrate. Coulomb islands are formed in the juxtaposed edges of a first substrate and second substrate, respectively. The islands generate edge Coulomb forces. These edge Coulomb forces can be used to detach, repel, move, attract and reattach the edges of substrates into new configurations. One possibility is to combine a plurality of individual substrates into one large planar substrate. | 06-11-2009 |
20090147433 | LEVITATING SUBSTRATE BEING CHARGED BY A NON-VOLATILE DEVICE AND POWERED BY A CHARGED CAPACITOR OR BONDING WIRE - At least one non-volatile device is coupled to a first Coulomb island. The floating gates of these non-volatile devices are connected to the island and can charge the Coulomb islands. One device can charge the island positively while a second device can be used to charge the island negatively. The Coulomb island can have a small probe opening where a charge can be introduced by using mechanical means such as an external probe or a MEMS switch. A fully charged capacitor formed in a first substrate can provide additional energy to a levitated substrate if the first substrate is connected to the levitated substrate. Bonding wires can be attached to a substrate that is attached to a mother substrate. Then, Coulomb forces can levitate the substrate from the mother substrate and the bonding wires can provide a source of power to the levitated substrate. | 06-11-2009 |
20090147434 | USING MULTIPLE COULOMB ISLANDS TO REDUCE VOLTAGE STRESS - A substrate is levitated a first distance over a mother substrate when a first group of Coulomb islands are charged. A second group of Coulomb islands are charged and increase a separation to a second distance. When the magnitude of the potential of all Coulomb islands is decreased, the separation decreases from the second distance to the first distance. All potentials associated with the Coulomb islands have decreased yet the distance of separation equals to the first distance. Increasing the number of Coulomb islands in a substrate can reduce the magnitude of potentials applied to the Coulomb islands thereby reducing the concern of voltage stress. | 06-11-2009 |
20090147435 | PARTICLE TRAP - An apparatus and method for trapping particles in a housing is disclosed. A high voltage terminal/structure is situated within a housing. A conductive material, having a plurality of holes, such as a mesh, is disposed a distance away from an interior surface of the housing, such as the floor of the housing, forming a particle trap. The conductive mesh is biased so that the electrical field within the trap is either non-existent or pushing toward the floor, so as to retain particles within the trap. Additionally, a particle mover, such as a fan or mechanical vibration device, can be used to urge particles into the openings in the mesh. Furthermore, a conditioning phase may be used prior to operating the high voltage terminal, whereby a voltage is applied to the conductive mesh so as to attract particles toward the particle trap. | 06-11-2009 |
20100271744 | SYSTEM AND METHOD OF SENSING AND REMOVING RESIDUAL CHARGE FROM A PROCESSED WAFER - Systems and methods for removing residual charge from a processed wafer are described. Removal of residual charge eliminates de-chucking failure that may break or damage the wafer. Residual charge is removed by applying a reverse polarity discharging DC voltage to an electrode embedded in an electrostatic chuck (ESC) supporting the wafer, and providing an outlet to the residual charge to ground via a lift pin assembly. Lift pin assembly is kept at the same potential with respect to a pedestal of the ESC to avoid sparking during the application of RF power to generate plasma. A residual charge sensor is included to sense and measure the amount of residual charge, so that the parameters of the reverse polarity discharging voltage can be adjusted in a subsequent de-chucking operation. | 10-28-2010 |
