“…This feature makes the rf discharge suitable for application in different material processing areas. [19][20][21][22][23][24] The experimental parameters varied are operating power (10 W to 120 W) and pressure (10 mTorr to 350 mTorr). The three measured quantities, i.e., I rms , V rms , and average power P are used to calculate the reduction of the bulk plasma resistance as well as the deviation of the I rms from the homogeneous discharge model.…”

Self-excited plasma series resonance is observed in low pressure capacitvely coupled radio frequency discharges as high-frequency oscillations superimposed on the normal radio frequency current. This high-frequency contribution to the radio frequency current is generated by a series resonance between the capacitive sheath and the inductive and resistive bulk plasma. In this report, we present an experimental method to measure the plasma series resonance in a capacitively coupled radio frequency argon plasma by modifying the homogeneous discharge model. The homogeneous discharge model is modified by introducing a correction factor to the plasma resistance. Plasma parameters are also calculated by considering the plasma series resonances effect. Experimental measurements show that the self-excitation of the plasma series resonance, which arises in capacitive discharge due to the nonlinear interaction of plasma bulk and sheath, significantly enhances both the Ohmic and stochastic heating. The experimentally measured total dissipation, which is the sum of the Ohmic and stochastic heating, is found to increase significantly with decreasing pressure.

“…5. At P 1 = 0.27 Pa, the grains are elongated, which is a typical morphology for films deposited using a low pressure [22]. At P 1 = 1.30 Pa, the morphology is similar but the inter-granular voids become wider, resulting in a less compact structure.…”

“…Due to this "self bias" the ion energies near the power electrode reaches up to few hundred eV. This feature makes the rf discharge suitable for application in different material processing areas [2,[15][16][17][18][19]. The experiment is carried out in 35 mtorr chamber pressure and the rf power is varied from 10 watt to 120 watt.…”

Abstract-Low temperature radio frequency plasma is widely used in low temperature plasma processing medium for material processing in many fields including microelectronics, aerospace, and the biology. For proper utilization of the process, it is very much important to know the plasma parameters. In this paper a technique is reported to determine the plasma parameters from the electrical discharge characteristic of a capacitivly couple radio frequency argon plasma. The homogeneous discharge model is modified to make it applicable in low pressure by incorporating the plasma series resonance effect. The effect on the plasma resistance by the change in drift velocity of the electron with rf electric filed is also considered. The electron density and temperature is found to be well agreed with the Langmuir probe diagnostic result, which is in the range of 0.5x10 10 to 4.5x10 10 cm -3 and 1.4 to 1.6 ev for wide range of rf power.Index Terms-Capacitive couple radio frequency plasma, discharge characteristic, homogeneous discharge model, plasma parameters, power balance.
