Abstract
Official abstract text for this publication.
A dielectric film containing an alkaline earth metal oxide having a NaCl type crystal structure as a main component, wherein the dielectric film has a (111)-oriented columnar structure in a direction perpendicular to the surface of the dielectric film, and in a Cu—Kα X-ray diffraction chart of the dielectric film, a half width of the diffraction peak of (111) is in a range of from 0.3° to 2.0°.
First claim
Opening claim text (preview).
1 . A dielectric film, comprising an alkaline earth metal oxide having a NaCl type crystal structure as a main component, wherein the dielectric film has a (111)-oriented columnar structure in a direction perpendicular to the surface of the dielectric film, and in a Cu—Kα X-ray diffraction chart of the dielectric film, a half width of the diffraction peak of (111) is in a range of from 0.3° to 2.0°. 2 . The dielectric film according to claim 1 , wherein the dielectric film contains at least one element selected from the group consisting of Ta, Nb, V, Hf, Zr, Ti and Zn as a subcomponent. 3 . The dielectric film according to claim 2 , wherein when the total content of the subcomponents is set as x, the x is in the range of 0 mol %<x≦20 mol % relative to the main component. 4 . An electronic component comprising the dielectric film according to claim 1 . 5 . An electronic component comprising the dielectric film according to claim 2 . 6 . An electronic component comprising the dielectric film according to claim 3 .
