MULTI-LAYER THIN FILM FOR OPTICAL INTERFERENCE INLIGHT-EMITTING DIODES

摘要

PURPOSE: A thin film for preventing optical interference reflection light of light emitting diodes is provided to perform a manufacturing process and to prevent efficiently reflection light by using a low-temperature deposition method. CONSTITUTION: A thin film for preventing optical interference reflection light includes a lamination structure of a semitransparent metal thin film, an optical transmitting thin film, and a full reflection metal thin film, The optical transmitting thin film is composed of a compound of group I-VII. The compound of group I-VII is KCl or KBr. The optical transmitting thin film is formed with the thickness of 50-700Å. The semitransparent thin film is formed with a metal thin film of 10-200Å.
