Abstract:
In a refrigerator door in which a decoration member is mounted to a door frame using a foam material, the foam material fills a space formed between the decoration member mounted to a front side of the door frame and a rear panel mounted to a rear side of the door frame. Accordingly, the decoration member can be fixed to the door frame through direct contact with the foam material.
Abstract:
A method of manufacturing a semiconductor light emitting device, includes sequentially growing a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer on a substrate to form a light emitting layer. The forming of the light emitting layer includes a first growth process, a second growth process and a transfer process. The first growth process uses a first susceptor having a mounting surface with a first curvature. The second growth process uses a second susceptor having a mounting surface with a second curvature different from the first curvature. The transfer process transfers the substrate from the first susceptor to the second susceptor between the first and second growth processes.
