Abstract:
1. A method of manufacturing a dielectric film comprising: forming a dielectric precursor film by coating sol made of an organic metal compound on a lower layer; drying the dielectric precursor film; degreasing the dielectric precursor film; and baking the dielectric precursor film for crystallization to form a dielectric film, wherein the drying includes: wherein a rate of temperature rise in the degreasing is the range from 0.5 to 1.5 (degrees C./sec), wherein a temperature to be attained in the degreasing is higher by a temperature selected from a range from 100 degrees C. to 300 degrees C. than the boiling point of the solvent which is the main solvent of the sol, and wherein a temperature of the baking is 680 degrees C. or above.
