Abstract
Abstract A method of forming a dielectric thin film pattern, comprises the steps of: depositing a dielectric thin film on a substrate having a resist pattern thereon by a vapor deposition method, wherein as a material for the dielectric thin film, at least one of CeO 2 , Sm 2 O 3 , Dy 2 O 3 , Y 2 O 3 , TiO 2 , Al 2 O 3 , and MgO is used; and removing the resist pattern whereby the dielectric thin film is patterned.
