An emitter for an electron-beam projection lithography system includes a photoconductor substrate, an insulating layer formed on a front surface of the photoconductor substrate, a gate electrode layer formed on the insulating layer, and a base electrode layer formed on a rear surface of the photoconductor substrate and formed of a transparent conductive material. In operation of the emitter, a voltage is applied between the base electrode and the gate electrode layer, light is projected onto a portion of the photoconductor substrate to convert the portion of the photoconductor substrate into a conductor such that electrons are emitted only from the partial portion where the light is projected. Since the emitter can partially emit electrons, partial correcting, patterning or repairing of a subject electron-resist can be realized.
