Abstract

A substrate heating apparatus is provided. The substrate heating apparatus includes a chamber, a substrate supporting unit configured to support at least one substrate where a thin film is formed on the top surface thereof, and at least one heating unit disposed in a region adjacent to the rear surface of the substrate. The heating unit includes a plurality of reflecting units arranged under the substrate, at least one lamp heating unit disposed inside the plurality of reflecting units, and a short- wavelength blocking layer disposed on the lamp heating unit. By providing the lamp heating unitunder the substrate where the thin film or pattern is formed on the top surface, and supplying heat energy to the rear surface of the substrate, it is possible to prevent the degradation in efficiency of the thin film, such as degradation of the thin film formed on the top surface of the substrate due to the heat source or the peeling of the thin film due to the temperature deviation between thesubstrate and the thin film. Furthermore, the heat energy is widely spread out at the central region of the rear surface of the substrate, and the heat energy is focused at the edge region of the substrate, thereby heating the large-sized substrate uniformly.

Description

technical field [0001] The present invention relates to a substrate heating device, and more particularly to a substrate heating device for preheating a large substrate that has been surface treated or that a thin film is deposited thereon. Background technique [0002] Generally, since a large substrate has a slow rate of temperature increase, it is heated to a processing temperature in a preheating chamber (ie, a substrate heating device) before main processing. That is, in the case where an unheated substrate is loaded into the chamber for main processing, additional processing time for heating the substrate is required. In addition, if a low-temperature substrate is loaded into a high-temperature main chamber, the substrate may be thermally damaged and the internal temperature of the main chamber decreases. [0003] Therefore, according to the related art, providing figure 1 The substrate heating apparatus illustrated in is used to preheat the substrate. [0004] refe...
