  • Patent number: 12078515
    Abstract: Disclosed is linear displacement absolute position encoder used for measuring displacement of a tested apparatus. The linear displacement absolute position encoder comprises a base, a magnetoresistive sensor array, an encoding strip, and a back magnet. The encoding strip is fixed on the base and extends in the direction of a rail of the tested apparatus. The encoding strip is a magnetic material block having recess and protrusion for identifying encoding information of different positions. The magnetoresistive sensor array is arranged between the encoding strip and the back magnet in a non-contact manner. The back magnet is used for generating a non-uniform magnetic field around the encoding strip so as to magnetize the encoding strip. The magnetoresistive sensor array is used for acquiring the position encoding information of the encoding strip by detecting magnetic field information of the encoding strip. The encoder is low cost and can monitor large distances.

  • Publication number: 20210343506
    Abstract: Apparatus and methods for processing a workpiece using a plasma are provided. In one example implementation, an apparatus can include a processing chamber. The apparatus can include a plasma chamber comprising a dielectric tube defining a sidewall. The apparatus can include an inductively coupled plasma source. The inductively coupled plasma source can include an RF generator configured to energize an induction coil disposed about the dielectric tube. The apparatus can include a separation grid separating the processing chamber from the plasma chamber. The apparatus can include a controller configured to operate the inductively coupled plasma source in a pulsed mode. During the pulsed mode the RF generator is configured to apply a plurality of pulses of RF power to the induction coil. A frequency of pulses can be in a range of about 1 kHz to about 100 kHz.

  • Patent number: 10964528
    Abstract: Processes for surface treatment of a workpiece are provided. In one example implementation, organic radicals (e.g., methyl CH3 radicals) can be generated by exciting and/or dissociating hydrogen and/or inert gas (e.g., Ar, He, etc) molecules in a remote plasma source and a subsequent reaction with organic molecule (alkanes and alkenes). The organic radicals (e.g., methyl CH3 radicals) can be exposed to the silicon and/or silicon germanium surfaces. After exposure to the organic radicals, the silicon and/or silicon germanium surfaces can be stable in air for a time period (e.g., days) with reduced surface oxidation such that the silicon and/or silicon germanium surfaces can be effectively protected from oxidation. As such, native surface oxide removal process before subsequent process steps can be eliminated.
