METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE
A method of manufacturing a semiconductor device includes a first laminating step, a second laminating step, a third laminating step, a first annealing step, and a fourth laminating step. In the first laminating step, a first electrode film is laminated on a substrate. In the second laminating step, a capacitive insulator is laminated on the first electrode film. In the third laminating step, a metal oxide is laminated on the capacitive insulator. In the first annealing step, the first electrode film, the capacitive insulator, and the metal oxide, which are laminated on the substrate, are annealed. In the fourth laminating step, a second electrode film is laminated on the annealed metal oxide. The capacitive insulator is an oxide that contains at least one of zirconium and hafnium, and the metal oxide is an oxide that contains at least one of tungsten, molybdenum, and vanadium.
