  • Publication number: 20210313152
    Abstract: A substrate processing system includes a plasma generator configured to supply (radio frequency) RF power to an electrode arranged in a processing chamber. A sensor is configured to sense a parameter of the RF power supplied to the electrode. A controller is configured to compensate variations in a rate of a plasma process due to variations in bulk resistivity of a substrate arranged on a substrate support by causing the sensor to sense the parameter at least one of prior to plasma processing of the substrate and after a predetermined period after the plasma processing of the substrate begins; and adjusting the parameter of the RF power for the substrate during the plasma processing of the substrate based on the parameter sensed for the substrate.

  • Patent number: 9881788
    Abstract: The embodiments disclosed herein pertain to methods and apparatus for depositing stress compensating layers and sacrificial layers on either the front side or back side of a substrate. In various implementations, back side deposition occurs while the wafer is in a normal front side up orientation. The front/back side deposition may be performed to reduce stress introduced through deposition on the front side of the wafer. The back side deposition may also be performed to minimize back side particle-related problems that occur during post-deposition processing such as photolithography.

  • Publication number: 20170170018
    Abstract: Well-controlled, conformal doping of semiconductor substrates may be achieved by low temperature hydrogen-containing plasma treatment prior to gas phase doping. Substrates doped in this manner may be capped and annealed for thermal drive-in of the dopant. The technique is particularly applicable to the formation of ultrashallow junctions (USJs) in three-dimensional (3D) semiconductor structures, such as FinFET and Gate-All-Around (GAA) devices.

  • Patent number: 9466502
    Abstract: A method for forming lines in an etch layer on a substrate may comprise providing a ultra-violet (UV) producing gas to a vacuum chamber having a photoresist mask, ionizing the UV producing gas to produce UV rays to irradiate the photoresist mask, and etching the lines into the etch layer through the photoresist mask.
