摘要： A capacitor includes an electrode and a dielectric layer over the electrode. The dielectric layer includes plural metal oxide particles which are spread, and have an aperture constituted by a space provided between the metal oxide particles. The capacitor further includes an insulating portion on a portion of the electrode facing an opening of the aperture of the dielectric layer. The insulating portion covers the opening of the aperture. This capacitor prevents short-circuiting between the electrodes, thus being highly reliable.
