Apparatus and methods for electron beam lithography using array cathode

One embodiment relates to an apparatus for electron beam lithography. The apparatus includes an array of cold cathode electron sources for generating an array of electron beams, and driver circuitry underlying the array of electron sources. The driver circuitry is configured to selectively blank individual electron beams so as to create a patterned array of electron beams. The apparatus further includes an imaging system configured to focus and demagnify the patterned array of electron beams and a movable stage for holding a target substrate. The movable stage is configured to translate the target substrate under the patterned array of electron beams. A computer may be configured to send drive signals to the driver circuitry to cause a pattern to be written onto the target substrate to roll across the array in synchronization with the translation of the target substrate. Other embodiments, aspects and feature are also disclosed.
