  • Patent number: 10923379
    Abstract: An insulator-type substrate is positioned on a support surface of a substrate support structure in exposure to a plasma. An initial clamping voltage is applied to an electrode within the substrate support structure to rapidly accumulate electrical charge on the support surface to hold the substrate. A backside cooling gas is flowed to a region between the substrate and the support surface, and a leak rate of the backside cooling gas is monitored. A steady clamping voltage is applied to the electrode, and the steady clamping voltage is adjusted in a step-wise manner to maintain the monitored leak rate of the backside cooling gas at just less than a maximum allowable leak rate. Or, a pulsed clamping voltage is applied to the electrode, and the pulsed clamping voltage is adjusted to maintain the monitored leak rate of the backside cooling gas at just less than the maximum allowable leak rate.
    Type: Grant

  • Patent number: 9738889
    Abstract: A syringe device having a plunger beneath which is disposed a rupturable capsule containing a nucleic acid wash buffer and a rupturing mechanism for rupturing the capsule, wherein the capsule, syringe, plunger, and rupturing mechanism are so configured as to first apply pneumatic pressure to force a nucleic acid solution through a membrane and to thereafter rupture the capsule and force a first volume of the wash buffer through the membrane.

  • Publication number: 20070205280
    Abstract: A method and system for collecting, storing, and processing automatic identification code information includes receiving automatic identification code information and parsing it based on stored definitions for automatic identification codes and/or automatic identification code standards. Various data configurations may be used to store definitions and to facilitate parsing of raw automatic identification code data. For example, a first component may be used for generally defining one or more automatic identification code standards and a second component may be used for detailed information regarding code definitions, such as information relating to code segments. In addition, the system may facilitate further processing of parsed automatic identification code information, such as for cycle counting or parts movement of inventory.
