Abstract:
PURPOSE: A UV nano implant lithography device with a temperature control function and a temperature control method are provided to improve accuracy of a pattern by minimizing thermal expansion difference between a mold and a substrate due to heating of a polymer resin. CONSTITUTION: A thermocouple and a heating line are installed on a thermostat plate. A chamber(4) receives a loading plate, a thermostat plate, and a pressure unit in a receiving space which is opened through a door. A temperature sensor(5) is installed inside the chamber to measure an inner temperature of the chamber. An external air handing unit constantly maintains the inner temperature of the chamber by circulating the air inside a chamber. A control board controls the operation of the external air handing unit and controls the temperature of the thermostat plate based on temperature data measured by a thermo couple and a temperature sensor.

PURPOSE: A substrate alignment stage for a UV nano imprint device is provided to minimize the change of a substrate by uniformly distributing an adsorption nozzle along the edge of an alignment stage when fixing the substrate on an adsorption plate. CONSTITUTION: An adsorption plate(10) has a flat upper side in which a substrate is received. A vacuum hole(12) is formed on the upper side of the adsorption plate and is connected to a vacuum exhaust pipe through a vacuum path formed inside the absorption plate. An adsorption nozzle(14) is recessed on the upper side of the adsorption plate from the vacuum hole exposed to the upper side of the adsorption plate and forms vacuum pressure for vacuum adsorption of the substrate between the substrate received in the adsorption plate and the adsorption plate.
Abstract:
A temperature controller of a nano imprint apparatus and a nano imprint apparatus including the same are provided to reduce a manufacturing cost of the nano imprint apparatus by controlling arbitrarily and freely an installation position. A heat exchange pin(100) is composed of a heat-conducting material and includes a plurality of air flow paths. A first thermoelectric module(200) is coupled with the one side of the heat exchange pin in order to connect a heat-absorbing reaction part. A second thermoelectric module(300) is coupled with the heat exchange pin in order to connect a heat-radiating reaction part with the other side of the heat exchange pin. An air suction tube(400) is used for forming an air suction path from the inside of the chamber to the air flow path of the heat exchange pin. An air discharge tube(500) is used for forming an air returning path to the inside of the chamber through the heat exchange pin. A temperature sensor(600) senses the temperature of the air through the air suction tube or the air discharge tube. A temperature control unit(700) compares the temperature received from the temperature sensor with the reference temperature and supplies selectively the power to the first and second thermoelectric modules.
