An apparatus of forming a fine pattern includes a chamber having a predetermined process space, a stage for supporting a substrate on which a photosensitive organic layer is formed, using buoyancy, a template disposed away from the stage to imprint a preprocess pattern dividing etching and non-etching regions on the organic layer of the substrate, and a driving unit for moving the stage toward the template so that the pattern formed on the template can be formed on the organic layer of the substrate.

Apparatus for forming fine pattern on substrate

A cassette assembly and a method of manufacturing fluorescent lamps using the cassette assembly are provided. The cassette assembly includes a housing defining a process chamber and having a plurality of holes in which glass tubes for the fluorescent lamps are inserted to communicate with the chamber, a carrying unit including two or more porous plates through which the glass tubes are fitted, a plurality of ring members disposed on the porous plates to preliminarily fix the glass tubes to the carrying unit by allowing the outer circumferences of the glass tubes to contact, and a locking unit for changing the glass tubes from the preliminary fixing status to a lockup status by varying contact pressure applied between the ring members and the glass tubes.

Cassette assembly for manufacturing fluorescent lamps

A method of fabricating an electrode of an external electrode fluorescent lamp (EEFL) includes plating nickel on both ends of a glass tube through an electroless nickel plating process and forming electrodes by dipping the glass tube into an electrode material including zinc, and tin or lead.

Method for fabricating electrode of external electrode fluorescent lamp and external electrode fluorescent lamp having electrode fabricated by the method

There is provided a fluorescent material coating apparatus for a fluorescent lamp. The fluorescent material coating apparatus includes a cassette on which a plurality of glass tubes are detachably mounted, a delivery member having a delivery chamber communicating with first ends of the glass tubes, a negative pressure generating unit for allowing fluorescent solution to be drawn into the glass tubes by generating a negative pressure in the glass tubes communicating with the delivery chamber by lowering the pressure of the delivery chamber, a dry air supplying unit for supplying dry air to the delivery chamber to dry the fluorescent solution applied on inner surfaces of the glass tubes, a solution tank containing the fluorescent solution and disposed below the glass tubes mounted on the cassette, and a moving unit for allowing lower end portions of the glass tubes mounted in the delivery chamber to be dipped into the fluorescent solution contained in the solution tank.
