As described above, the CVD film formation temperature was set at 500 ° C. Even when the deposition temperature was 400, nitrogen could be taken in. At a deposition temperature of 400 ° C- 600 ° C, A l 2 0 3, H f 0 2, H: it would be possible to incorporate nitrogen into f A L_ ⁇ . Increasing the atmospheric pressure during film formation tended to worsen the in-plane distribution of the high dielectric constant film. It is preferable that the atmospheric pressure during the film formation be 10 Pa to 100 Pa.
