Abstract

See full text

A dielectric film may be exposed to an acid solution such as hydrochloric acid, nitric acid, or sulfuric acid during a wet process after film formation. The inventors have newly found that when a dielectric film includes Zr having a lower ionization tendency than Ti in a main component of a metal oxide expressed by a general formula (Ba, Ca)(Ti, Zr)O3 is provided and satisfies at least one between relationships such that degree of orientation of (100) plane is higher than degree of orientation of (110) plane, and degree of orientation of (111) plane is higher than degree of orientation of (110) plane in a film thickness direction, the dielectric film is less likely to be damaged during a wet process, and the resistance to a wet process is improved.
