Abstract
A method of fabricating a capacitor includes selectively forming a positive photosensitive resin layer on a first conductive layer; exposing the positive photosensitive resin layer, immersing the exposed positive photosensitive resin layer in a solution in which dielectric particles are dispersed and diffusing the dielectric particles into the positive photosensitive resin layer; forming an insulating resin layer covering side faces of the positive photosensitive resin layer; and forming a second conductive layer on the positive photosensitive resin layer. According to the method, a very reliable capacitor having excellent electrical characteristics, such as dielectric strength, can be cheaply and easily fabricated in a wiring layer.
