Semiconductor light emitting device and method for manufacturing the same

A method for manufacturing a semiconductor light emitting device, the method comprising the steps of:

• forming a first semiconductor layer on a substrate;
• forming an active layer on the first semiconductor layer;
• forming a second semiconductor layer on the active layer;
• partially etching the active layer and the second semiconductor layer until the first semiconductor layer is exposed;
• heating the substrate on which the first semiconductor layer, the active layer and the second semiconductor layer are formed;
• forming a light transmissive electrode layer on the second semiconductor layer, the light transmissive electrode layer including at least one conductive thin film and at least one insulating thin film,
• wherein the step of forming the light transmissive electrode layer includes:
• forming a first conductive thin film on the second semiconductor layer;
• forming a first insulating thin film on the first conductive thin film;
• forming a second conductive thin film on the first insulating thin film;
• forming a second insulating thin film on the second conductive thin film;
• and
• forming one or more contact portions by partially etching the first insulating thin film, the second conductive thin film and the second insulating thin film until the first conductive thin film is exposed without etching the first conductive thin film;
• and
• forming a first electrode being in contact with the first and second conductive thin films through the one or more contact portions and forming a second electrode on the first semiconductor layer on which the active layer and the second semiconductor layer are not formed,
• wherein the first and second conductive thin films and the first and second insulating thin films are formed with the same pattern,
• wherein the step of heating the substrate is performed between the step of partially etching the active layer and the second semiconductor layer and the step of forming the light transmissive electrode layer.
