Simulation of Magnetically Confined Inductively Coupled Plasma
… presented to address the need for high density inductively coupled plasmas with enhanced properties and a more uniform and consistent distribution, suitable for large-area material processing. Fluid model simulations of 3D argon inductively coupled plasma (ICP) were performed in COMSOL for the …

FLUORESCENCE STUDIES IN THE INDUCTIVELY COUPLED PLASMA
… searches were used to optimise several plasma parameters, i.e. forward power; viewing height ALC; plasma, nebuliser and auxiliary gas flow rates. Once the optimum conditions had been determined, calibration curves were plotted for each of the elements studied (Ba, Li, Mg and Na). The …

Inductively Coupled Plasma Etching of III-N Semiconductors
… of an in-house designed and constructed inductively coupled plasma (ICP) system for integrated studies pertaining to the etching rates and etching selectivity among AlN, GaN, and Al(x)Ga(1-x)N. An (ICP) system was chosen because of its high plasma density and low cost relative to other …
