  • Patent number: 7981259
    Abstract: A method and apparatus for adjusting an electric field of an electrochemical processing cell are provided. In one embodiment, a capacitive element is disposed in the processing solution. The strength, shape, or direction of the electric field in the processing solution may be modulated by charging and discharging the capacitive element in a controlled manner. Because the electric field is modulated with out passing a current from the capacitive element to the processing solution, electrochemical reactions do not occur on the interface of the capacitive element and the processing solution, thus, reduces complications caused by unwanted electrochemical reactions.

  • Patent number: 7977199
    Abstract: Embodiments of the invention generally provide methods for end point detection at predetermined dopant concentrations during plasma doping processes. In one embodiment, a method includes positioning a substrate within a process chamber, generating a plasma above the substrate and transmitting a light generated by the plasma through the substrate, wherein the light enters the topside and exits the backside of the substrate, and receiving the light by a sensor positioned below the substrate. The method further provides generating a signal proportional to the light received by the sensor, implanting the substrate with a dopant during a doping process, generating multiple light signals proportional to a decreasing amount of the light received by the sensor during the doping process, generating an end point signal proportional to the light received by the sensor once the substrate has a final dopant concentration, and ceasing the doping process.

  • Patent number: 7971650
    Abstract: A method of pumping wellbore fluid, comprising the steps of: installing an electric submersible pump in a wellbore; and operating the pump at more than 4,500 rpm to pump the wellbore fluid. Pumping in this manner provides a number of advantages in use in that the required high-speed motor and pump is shorter for a given power than existing arrangements, and provides increased reliability due to reduced complexity. A much shorter motor/pump combination also allows such equipment to be used in deviated boreholes with a reduction in damage due to mishandling and bending, as well as facilitating assembly and testing in the manufacturer's plant.
