Abstract
A novel post-hydrogenation method for chemical-vapor-deposited amorpho us-silicon (CVD a-Si) thin-film transistors (TFTs) has been proposed. Samples were annealed in the presence of the atomic hydrogen generated by a hot tungsten filament. The dependence of the amount of adsorbed hydrogen on annealing period, filament temperature and total gas press ure was described. A-Si TFTs which were post-hydrogenated by means of the hot-filament method showed an electron mobility of 1.1 cm2/V . s. The lifetime and diffusion length of atomic hydrogen were estimated.
