Semiconductor-light emitting apparatus i.e. LED-device, for use as e.g. backlight unit of large TV, has contact hole connected with semiconductor layer and extending from surface of electrode layer to part of semiconductor layer

摘要

The apparatus (100) has a conductive substrate (150), and an exposed region formed on a boundary surface between an electrode layer (120) and a conductivity type semiconductor layer (111) that includes another electrode layer (140) and a contact hole (114). The contact hole is electrically connected with another conductivity type semiconductor layer (113), and located opposite to the former conductivity type semiconductor layer and active layers (112). The contact hole extends from a surface of the latter electrode layer to a part of the latter conductivity type semiconductor layer. An independent claim is also included for a method for manufacturing a semiconductor-light emitting apparatus.
