Abstract:
An apparatus for providing a one-to-one projection of pyroelectric emission lithography, comprising:a plate type emitter formed of a pyroelectric material; a mask stacked on the plate type emitter in a desired pattern, the mask allowing electrons to be emitted from the plate type emitter in a desired pattern; a substrate which carries an object to be etched to form the desired pattern; an electron resist deposited on the substrate, the electron resist being sensitive to the emitted electrons; a heating source for heating the plate type emitter; a power supply for applying a voltage between an emitter structure and the object to be etched to allow the electrons to be emitted from the emitter structure and applied to the object to be etched, the emitter structure comprising the plate type emitter and the mask, and the object to be etched comprising the substrate and the electron resist; and magnets disposed outside the emitter structure and the object to be etched, the magnets controlling the path of the electrons emitted from the emitter structure towards the object to be etched.
