简介 Increasing the number of successive pulses of oxidant before applying pulses of metal precursor may improve the quality of the resulting metal or rare earth oxide films. These metal or rare earth oxide films may be utilized for high dielectric constant gate dielectrics. In addition, pulsing the oxidant during the pre-stabilization period may be advantageous. Also, using more pulses of oxidant than the pulses of precursor may reduce chlorine concentration in the resulting films.
