<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a capacitor having a dielectric layer having a high dielectric constant, and preventing leakage current from deteriorating by a large amount. <P>SOLUTION: The capacitor manufacturing method comprises an application process for forming an application film, by applying a dielectric precursor solution containing titanium, barium, strontium, and a group IA element to the surface of a base material; and a heat treatment process for performing heat treatment on the application film at 700 to 900°C to obtain a high dielectric film. The high dielectric film contains the group IA element of 1.5 to 5 pts.wt. with respect to the dielectric substance of 100 pts.wt. <P>COPYRIGHT: (C)2007,JPO&INPIT |
