Abstract:
A nano-pattern lithographic fabrication apparatus, comprising:a container for receiving a nano-pattern generating solution therein; a sample on which a pattern is formed by the solution; a container controlling unit for controlling the movement of the container and ejecting the nano-pattern generating solution filled in the container on the sample, wherein said container controlling unit comprises: a first displacement generating unit for vibrating the container at a resonant frequency; and a second displacement generating unit for pressurizing the container thereby ejecting the nano-pattern generating solution therefrom; a sample moving unit for supporting and moving the sample; a detector for detecting a distance between a dispensing end portion of the container and a surface of the sample; and a controlling unit for receiving a detection signal from the detector and controlling the movement of the container and the sample moving unit and a distance there between.
