Abstract: Systems and methods for redirecting cleaning chemistry flows within a multi-station semiconductor processing chamber are disclosed. In such systems, a cleaning chemistry flow, e.g., a plasma from a remote plasma generator, may be directed onto a hub of an indexer that is centrally mounted within the chamber. The hub may have features that cause the cleaning chemistry flows to be redirected in a radially outward direction. By rotating the hub and/or changing the relative elevational positions between the hub and a cleaning chemistry inlet that provides the cleaning chemistry, the cleaning chemistry may be redirected into different regions of the chamber, thereby allowing for a more thorough and complete cleaning process.

Abstract: A method for extracting nucleic acids from a biological sample (such as plasma) using nanopores in a porous material. The method induces nucleic acids into nanopores of the porous material to achieve separation and purification of nucleic acids. The method also has the advantage that the bound nucleic acids will not separate from the pores under separation and cleaning conditions, and thus has good application prospects. The material containing nanopores can have added paramagnetic cores (for example, magnetic microspheres of ferroferric oxide) and be applied to a full-automatic nucleic acid extraction workstation to improve nucleic acid extraction efficiency.

The wafer is unclamped from the pedestal prior to the first and/or second deposition phase and remains unclamped during the first and/or second deposition phase. The wafer has a non-zero wafer bow during unclamped deposition phase to provide a radially non-uniform thickness profile of the film on the wafer.

A reset command is generated based on the output signal being greater than the analog input signal. The encoder splits a ripple associated with the reference voltage into multiple pulses in response to a reset command. The compensation circuit generates, responsive to the reset command, compensation pulses to compensate the multiple pulses.
