Digital chemical vapor deposition (CVD) method for forming a multi-component oxide layer

摘要

A chemical vapor deposition (CVD) method for forming a multi-component oxide layer. There is first provided a chemical vapor deposition (CVD) reactor chamber. There is then positioned within the chemical vapor deposition (CVD) reactor chamber a substrate. There is then formed over the substrate a multi-component oxide precursor layer. The multi-component oxide precursor layer is formed from at minimum a first precursor reactant source material and a second precursor reactant source material introduced simultaneously into the chemical vapor deposition (CVD) reactor chamber in absence of an oxidant reactant source material. There is then oxidized with the oxidant reactant source material within the chemical vapor deposition (CVD) reactor chamber the multi-component oxide precursor layer formed over the substrate to form a multi-component oxide layer formed over the substrate. The oxidant reactant source material is introduced into the chemical vapor deposition (CVD) reactor chamber in absence of the first precursor reactant source material and the second precursor reactant source material.
