Semiconductor light-emitting device |
摘要 |
A semiconductor light-emitting device including a light-emitting portion permitting light at a specific wavelength and having two surfaces opposite each other. The device also includes a first type of semiconductor substrate and a second type semiconductor substrate which are integrally joined to corresponding surfaces of the light-emitting portion and are substantially transparent to the wavelength. The semiconductor substrates have a joined surface on the surfaces of the light-emitting portion and outer side surfaces which have the width large on a side near the light-emitting portion and become narrow on a side away from the light-emitting portion and further surfaces opposite the joined surfaces. The device also includes first and second electrodes which are disposed on the corresponding further surfaces, a semiconductor layer in a region of at least one of the semiconductor substrates, and an impurity that causes current flow in concentrated manner through the middle of the light-emitting portion.
