  • Abstract
    The effects of ozone annealing on the trapping properties of Ta 2O5 deposited by LPCVD have been examined. It is concluded that the ozone annealing efficiently eliminates electron traps existing throughout the Ta2O5 film but generates hole traps. Structural or stoichiometric change induced by the ozone annealing is suggested as a reason
