A kinetic model, composed of elementary chemical reactions, is derived to predict the etch rate of crystalline silicon with NF3 in a plasma discharge.Experimental data taken from a radial flow plasma etching reactor is used to determine the model's kinetic parameters.The rate constant for atomic fluorine reacting with <100> silicon was determined to be 1410 cm/min at 25 °C, in good agreement with a value obtained by other investigators.
