Patent ID: 7513608

Claim:
A dielectric film structure having a substrate and a dielectric film provided on said substrate, wherein said dielectric film has (111) face orientation with respect to the substrate; and a value v in the following equation regarding said dielectric film is a real number greater than 2: v =( C 111 /C −110 )×( W −110 /W 111 ) where C 111 is a count number of a peak of a (111) face of said dielectric film in an out-of-plane X ray diffraction measurement; C −110 is a count number of a peak of a (−110 ) face of said dielectric film in an in-plane X ray diffraction measurement; W 111 is a half-value width of a peak of the (111) face of said dielectric film in an out-of-plane rocking curve X ray diffraction measurement; and W −110 is a half-value width of a peak of the (−110 ) face of said dielectric film in an in-plane rocking curve X ray diffraction measurement.
