摘要： Disclosed is an RFID interrogator having a collision type identification function and a control method thereof. It verifies whether or not a collision occurs in a received signal by analyzing data of a signal received from an RF communication unit and performs a corresponding collision resolution operation by diagnosing a collision type in accordance with a collision generation means between the corresponding RFID interrogator and other interrogators or a tag. Since all types of collisions that occur between the RFID interrogator and the tag can be identified, a reason for occurrence of the collisions can be rapidly recognized to cope with the reason for the collisions.

摘要： Provided are a nitride thin film structure and a method of forming the same. If a nitride thin film is formed on a substrate that is not a nitride, many defects are generated by a difference in lattice constants between the substrate and the nitride thin film. Also, there is a problem of warping the substrate by a difference in thermal expansion coefficients between the substrate and the nitride thin film. In order to solve the problems, the present invention suggests a thin film structure in which after coating hollow particles, i.e. hollow structures on the substrate, the nitride thin film is grown thereon and the method of forming the thin film structure. According to the present invention, since an epitaxial lateral overgrowth (ELO) effect can be obtained by the hollow structures, high-quality nitride thin film can be formed. Since a refractive index in the thin film structure is adjusted, there is an effect of increasing light extraction efficiency during manufacturing the thin film structure into a light emitting device such as a light emitting diode (LED). Also, when thermal expansion coefficient of the substrate is greater than that of the nitride thin film, total stress of the nitride thin film is decreased according to the compression of the hollow structures in the nitride thin film such that there is also an effect of preventing warpage of the substrate.
