Abstract
A method of fabricating hafnium oxide and/or zirconium oxide films is provided. The methods include providing a mixture of Hf and/or Zr alkoxide dissolved, emulsified or suspended in a liquid; vaporizing at least the alkoxide and depositing the vaporized component at a temperature of greater than 400° C. The resultant film is dense, microcrystalline and is capable of self-passivation when treated in a hydrogen plasma or forming gas anneal.
