This paper presents an investigation of argon capacitively coupled plasma at low pressure. A two-dimensional, time-dependent fluid model is used to describe the production, transport, and destruction of electrons and positive ions. The model is solved for a GEC(gaseous electronics conference) Cell reactor type (with 4cm diameter and 2.5cm interelectrode distance) operating at frequency 13.56MHz, pressure 1Torr and applied voltage 1000V, in pure argon. Two-dimensional distributions are presented in the stationary state, including electron temperature and species density i.e. electron, ion and metastable atom. The electric field and electric potential at different phases in one RF cycle is also studied.

Abstract Using a dusty plasma ratchet, one can realize the rectification of charged dust particle in a plasma. To obtain the ratchet potential dominating the rectification, here, we perform quantitative simulations based on a two-dimensional fluid model of capacitively coupled plasma. Plasma parameters are firstly calculated in two typical cross sections of the dusty plasma ratchet which cut vertically the saw channel at different azimuthal positions. The balance positions of charged dust particle in the two cross sections then can be found exactly. The electric potentials at the two balance positions have different values. Using interpolation in term of a double-sine function from previous experimental measurement, an asymmetrical ratchet potential along the saw channel is finally obtained. The asymmetrical orientation of the ratchet potential depends on discharge conditions. Quantitative simulations further reproduce our previous experimental phenomena such as the rectification of dust particle in the dusty plasma ratchet.

Low-pressure capacitively coupled plasmas are now widely used for plasma processing in the semiconductor technique. In this paper, a numerical simulation model was developed to simulate the plasma in a dual frequency capacitively coupled plasma reactor based on a two-dimensional, self-consistent fluid model. The aim of our work is to provide estimates of the main discharge and plasma parameters and to help understand the basic mechanisms governing the CCP etching devices. Accurate solutions of the continuity equations, electron energy balance equation and possion's equation with realistic boundary conditions are obtained. The numerical results are used to analyze the plasma density distribution for one and two dimensional on whole plasma reactor.
