Abstract
SIPOS films were deposited from a mixture of disilane and nitrous oxide in a tubular hot wall reactor and their thickness and oxygen content were measured. To increase one's knowledge in SIPOS deposition, a detailed chemical mechanism is proposed to represent homogeneous and heterogeneous reactions and the CVD2 model taking into account hydrodynamics and mass transfert with chemical reactions is adjusted to SIPOS deposition. A good agreement between experimental results and model predictions for various operating conditions puts in evidence the representativity of the chosen chemical mechanism. By the use of CVD2 model, the main chemical pathways are identified.
