Method and apparatus for pyroelectric lithography using patterned emitter
MetadataShow full item record
A method and an apparatus for pyroelectric lithography using a patterned emitter is provided. In the apparatus for pyroelectric lithography, a pyroelectric emitter or a ferroelectric emitter is patterned using a mask and it is then heated. Upon heating, electrons are not emitted from that part of the emitter covered by the mask, but are emitted from the exposed part of the emitter not covered by the mask so that the shape of the emitter pattern is projected onto the substrate. To prevent dispersion of emitted electron beams, which are desired to be parallel, the electron beams are controlled using a magnet or a projection system, thereby achieving exact a one-to-one projection or a x-to-one projection of the desired pattern etched on the substrate.
