Particle contamination in plasma processing is a serious and challenging issue for the semiconductor industry. In this work, Laser Doppler Velocimetry, Laser Light Scattering, and Optical Emission Spectroscopy are used to elucidate the physical behavior of particles trapped in a plasma. Coulomb theory is used to describe the motion of particles. The theory agreed very well with experimental data and was explored to evaluate conditions for which particle agglomeration is likely. Finally, it was observed that particles may fall out of the particle trap during plasma ignition and subsequently contaminate the substrate.
