20090146541 | INFRARED REFLECTOR AND HEATING DEVICE HAVING THE SAME - Provided is an infrared reflector having the configuration in which a dielectric film, an Au (gold) film, and an oxide film are sequentially formed on a substrate. The infrared reflector with this configuration is used so that the oxide film would face a body to be heated. In addition, infrared light emitted from a heat source can be reflected and collected by a reflection metal of the Au film to the body to be heated. Moreover, since the dielectric film is formed on the substrate, it is possible to prevent Au from dispersing under high temperature and thus to prevent deterioration of the infrared reflector. | 06-11-2009 |

The ZnO-based substrate is formed such that any one of a carboxyl group and a carbonate group is substantially absent in a principal surface on a crystal growth side. Also, in order for a carboxyl group or a carbonate group to be substantially absent, any one of oxygen radicals, oxygen plasma and ozone is brought into contact with the surface of the ZnO-based substrate before the crystal growth is started. Consequently, cleanness of the surface of the ZnO substrate is enhanced, thereby enabling fabrication of a high-quality ZnO-based thin film on the substrate. | 12-09-2010 |
