  • Patent number: 10381517
    Abstract: The present invention relates to a light emitting diode and a method for manufacturing same, and more specifically relates to growing a GaN layer of high quality on an upper part of an AlGaInP-based light emitting diode to improve the light extraction efficiency of the light emitting diode, wherein the GaN layer has a larger band gap and a smaller refractive index than AlGaInP-based material. The AlGaInP-based light emitting diode of the present invention is characterized by forming the GaN layer on the upper surface, and the GaN layer preferably has a surface of a fine uneven pattern. The GaN layer can be grown in the same system after forming the AlGaInP-based light emitting diode without an additional process.

  • Publication number: 20170132022
    Abstract: Disclosed are a file-processing device for executing a pre-processed file, and a recording medium for executing a related file-processing method in a computer. Once a request for registry information corresponding to the extension of a file is inputted according to a request for the execution of the file selected by the user, a registry-converting unit outputs a preset substitute value instead of the registry default value for executing a connection program corresponding to the extension of the file as the result value for the registry information request. A control unit pre-processes the file through a control program set in correspondence to the substitute value. A file-executing unit executes the file by executing the connection program of the file corresponding to the registry default value after pre-processing.
