The present invention discloses an apparatus for manufacturing electronic devices using a roll-to-roll rotary pressing process, comprising a winding roll around which flexible printing paper is wound; a plurality of printing units arranged in a straight line; at least one coating unit; a rewinding roll to rewind the printing paper when printing has been completed; a plurality of guide rolls arranged between the winding roll and the rewinding roll, thus guiding the printing paper; a plurality of drying units, each drying unit being provided on a printing paper-path between the printing unit and the adjacent guide roll to dry ink transferred to the printing paper or on a printing paper-path between the coating unit and the adjacent guide roll to dry the printing paper on which coating agent is supplied; and tension regulating units installed around the winding roll and the rewinding roll, respectively, for regulating tension of the printing paper.

Method and apparatus for manufacturing electronic device using roll-to-roll rotary pressing process

Disclosed herein is a method for forming a pattern, comprising: attaching a single-layer or multi-layer dry film resist made of a semi-solid or solid material to part or all of the surface of a substrate; exposing the dry film resist to light either by irradiating a focusable energy beam directly onto the resist or by projecting a specific wavelength range of light onto the resist, to form a region to be filled with a functional material; charging the functional material into the formed region using a method such as inkjetting; drying the functional material; and removing the dry film resist, thus obtaining the desired pattern.

Method for forming high-resolution pattern having desired thickness or high aspect ratio using dry film resist
