    Collisional, magnetic, and nonlinear skin effect in radio-frequency plasmas (2001)

    Notes: The penetration of radio-frequency energy into cylindrical devices is relevant to the production of uniform plasmas for etching and deposition processes in the production of semiconductor circuits. The so-called "anomalous skin effect" has been invoked to explain irregularities not predicted by classical electromagnetic theory. These expectations are summarized for the collisionality regimes of interest, and new results are given for nonkinetic effects caused by small direct current magnetic fields and the ponderomotive force. © 2001 American Institute of Physics.

    A floating potential method for measuring ion density (2002)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: A simple method for analyzing cylindrical Langmuir probe curves in a cold-ion plasma is described which yields the ion density in weakly collisional plasmas for which purely collisionless theories give erroneous results. The method is based on an extrapolation to the floating potential of the saturation ion current raised to the 4/3 power. This procedure is not supported by theory but apparently works because effects neglected in the theory tend to cancel. © 2002 American Institute of Physics.

    Langmuir probe analysis for high density plasmas (2001)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 8 (2001), S. 3029-3041

    Notes: High-density, radio-frequency plasmas used in semiconductor processing have progressed to densities n≥5×1011 cm−3, where the methods used to interpret Langmuir probe characteristics in low-density (109–11 cm−3) plasma reactors are no longer valid. Though theory and computations for arbitrarily dense collisionless plasmas exist, they are difficult to apply in real time. A new parametrization and iteration scheme is given which permits rapid analysis of Langmuir probe data using these theories. However, at high n, measured ion saturation curves are shown which do not agree in shape with the "correct" theory, yielding anomalously high values of n. The discrepancy with independent measures of n, which can exceed a factor of 2, is believed to be caused by charge-exchange collisions well outside the sheath. Probe designs for avoiding this discrepancy are suggested. © 2001 American Institute of Physics.
