Method for manufacturing high-brightness vertical light emitting diode

制造高亮度垂直式发光二极管的方法

Abstract

The invention relates to a method for manufacturing a high-brightness vertical light emitting diode. The method comprises the following steps of: forming a plurality of epitaxial material layers on a first patterned substrate, wherein a contact surface of the epitaxial material layers, which is contacted with the first patterned substrate, is a first surface, and a pattern corresponding to the first patterned substrate is formed on the first surface; arranging a second substrate on the epitaxial material layers; removing the first substrate to expose the first surface; planarizing the first surface to remove the pattern on the first surface corresponding to the first substrate so as to form a planar second surface; and forming a first electrode on the back side of the second substrate and forming a second electrode on the second surface, wherein the light emitting brightness of the component can be improved through proper surface roughening treatment.
本发明涉及一种制造高亮度垂直式发光二极管的方法,其包括在经图案化的第一基板上形成多个磊晶材料层,其中,该多个磊晶材料层与经图案化的第一基板接触面为第一表面,且该第一表面形成与该经图案化的第一基板相对应的图案;在该多个磊晶材料层上设置第二基板;移除该第一基板以曝露该第一表面;使该第一表面平坦化,以去除其上与该第一基板相对应的图案,由此形成平坦的第二表面;以及于该第二基板背侧形成第一电极并在该第二表面上形成第二电极,通过适当的表面粗化处理,可使该组件的发光亮度有所提升。
