摘要:
A method for forming a metal silicate as a high k dielectric in an electronic device, comprising the steps of: providing diethylsilane to a reaction zone; concurrently providing a source of oxygen to the reaction zone; concurrently providing a metal precursor to the reaction zone; reacting the diethylsilane, source of oxygen and metal precursor by chemical vapor deposition to form a metal silicate on a substrate comprising the electronic device. The metal is preferably hafnium, zirconium or mixtures thereof. The dielectric constant of the metal silicate film can be tuned based upon the relative atomic concentration of metal, silicon, and oxygen in the film.
