Abstract

Disclosed are a light emitting diode chip having a wavelength conversion layer, a method for manufacturing the same, and a package having the same. According to one aspect, the light emitting diode chip comprises: a substrate; a semiconductor stacked structure, which is located on an upper surface of the substrate and a gallium nitride-based compound semiconductor stacked structure including a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer; an electrode which is electrically connected to the semiconductor stacked structure; an additional electrode which is formed on said electrode; and a wavelength conversion layer which covers the upper part of the semiconductor stacked structure. Further, said additional electrode passes through the wavelength conversion layer. Thus, the invention is capable of performing wavelength conversion of light, and providing a light emitting diode chip which can easily bond a wire.

Description

technical field [0001] The invention relates to a light-emitting diode chip and its manufacturing method, as well as its package and its manufacturing method, in particular to a light-emitting diode chip with a wavelength conversion layer and its manufacturing method, as well as its package and its manufacturing method. Background technique [0002] Since the current light-emitting diodes have the advantages of being able to realize thinness, lightness and miniaturization, save energy and maintain life for a long time, they are being used as backlight sources for various display devices including mobile phones, and due to the advantages of mounting light-emitting diodes A light-emitting element (ie, a light-emitting diode package) can realize white light with high color rendering, and thus is expected to be applied to general lighting in place of white light sources such as fluorescent lamps. [0003] In addition, there are various methods of realizing white light using ligh...
