摘要:
A method for fabricating a capacitor includes: (1) forming a bottom electrode on a substrate; (2) forming a template layer on the bottom electrode; (3) performing a plurality of atomic layer deposition (ALD) cycles by using water vapor as an oxidant thereby depositing a first TiO2 layer on the template layer; and (4) performing ozone pulse and purge step to transform entire thickness of the first TiO2 layer into rutile phase.
