ELECTROHYDRODYNAMIC PATTERNING APPARATUS USING ELECTROMAGNETIC FIELD CONTROL AND PATTERNING APPARATUS USING THE SAME

摘要

The present invention relates to an electrostatic patterning apparatus using electromagnetic field control and a three-dimensional patterning apparatus using the same capable of improving precision and accuracy of a pattern by controlling an impact-landing direction and an impact-landing location of a fluid sprayed from a nozzle by using electromagnetic field control. The electrostatic patterning apparatus using electromagnetic field control comprises: a nozzle unit to spray a fluid towards a substrate; a voltage supply unit to form an electric field between the substrate and the nozzle unit, and to apply a voltage to the nozzle unit to spray the fluid from the nozzle unit; a magnetic field generation unit which is installed on a spray path of the fluid sprayed from the nozzle unit, has a hollow space formed in the middle thereof to allow the fluid to flow therethrough, and forms a magnetic field in the hollow space to move the fluid flowing through the hollow space straight forward towards the substrate in a concentrated state, or to adjust the spray path of the fluid to allow the fluid to land on a prescribed area of the substrate; and a control unit to adjust an intensity of the magnetic field formed by the magnetic field generation unit.
