Abstract :
Silicon nitride films were prepared by plasma-CVD from SiH4-N2and SiF4-N2-H2gas mixtures. These films exhibited lower hydrogen concentration and higher thermal endurance than those of the films deposited from the conventional SiH4-NH3gas mixture. Improved characteristics as encapsulant of MOSFET´s and as diffusion and annealing masks suggest usefulness of these films in the field of modern microelectronics processing.
