摘要：

Hydrogen transport in low-pressure chemical vapor deposited Si 3N4 has been investigated using samples consisting of a double layer of hydrogenated and deuterated nitride films. Concentration depth profiles of hydrogen and deuterium were measured using elastic recoil detection. Diffusion coefficients for D were derived from the deuterium concentration depth profiles before and after annealing at temperatures in the range 700-1000°C. The diffusion coefficient is characterized by an activation energy of 2.94 eV for the entire temperature range. Its value varies between 10-17 cm2/s at 700°C and 5×10-14 cm2/s at 1000°C.
