Abstract
Effects of the reactor temperature and TaCl5-precursor dose on the ato mic layer epitaxy (ALE) growth of tantalum oxide films are studied. It is shown that etching takes place instead of growth when high TaCl5 d oses are used. The etching rate is enhanced by increase of the reactor temperature. In the case of optimum precursor doses, a growth rate eq ual to 0.06 nm per cycle was obtained at 300 degrees C growth temperat ure.
