Abstract:
1. A method of manufacturing a dielectric thin film capacitor, the method comprising: applying a first dielectric raw material solution containing an organic metal compound on a substrate and heating the solution to form an adhesive layer; alternately depositing, on the adhesive layer, a conductor layer and a dielectric thin film formed by applying a second dielectric raw material solution with a composition system the same as that of the first dielectric raw material solution and heating the second solution to form a capacitor portion; applying, on the capacitor portion, a third dielectric raw material solution with a composition system the same as that of the first or second dielectric raw material solution and heating the third solution to form a crystalline dielectric barrier layer; heat treating at a temperature of 750° C. or more in an oxygen atmosphere; forming a non-conductive amorphous inorganic barrier layer on the dielectric barrier layer; and forming a resin protective layer on the inorganic barrier layer.
