Abstract
photosensitive resin composition of the present invention is prepared by adding inorganic particles having a functional group and a mean particle size smaller than the wavelength of light for exposure (e.g., about 1 to 100 nm) to a photosensitive resin. The inorganic particles can be of colloidal silica having a functional group. The photosensitive resin composition may be of positive or negative type, and developable with water or an alkali. The amount of the inorganic particles to be used is, relative to 100 parts by weight of the photosensitive resin, about 10 to 500 parts by weight on a solid matter basis. The use of such photosensitive resin composition makes it possible to largely improve oxygen plasma resistance, heat resistance, dry etching resistance, sensitivity, and resolution utilizing a conventional resist or lithography technique.
