Definitions
- H10-26095 As described above, in a device in which light emitted from a semiconductor light emitting device is reflected at the P-side electrode interface, not only light transmitted from the active layer to the substrate side but also light reflected at the p-side electrode interface as output light from the substrate side. , The luminous efficiency of the light emitting element can be increased. Further, the device described in JP-A-111-191641 and the semiconductor light-emitting device described in JP-A-2000-91616 function as a reflective layer. There is disclosed a structure in which a contact metal layer is formed between the electrode layer to be formed and the p-type semiconductor layer for achieving an ohmic contact.
- the thickness of the contact layer is, for example, about 50 nm, the reflectance is high. It is difficult to improve the luminous efficiency as a semiconductor light-emitting device, and the reflection structure itself including the contact metal layer is required to be improved.
- the present invention provides a semiconductor light emitting device and a method for manufacturing the same, which realize further higher luminous efficiency, and a connection structure of an electrode layer which realizes higher luminous efficiency. Aim.
- a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer are sequentially laminated on a light transmission type substrate, and light generated in the active layer is transmitted to the light transmission type substrate.
- an electrode layer is formed on the second conductivity type semiconductor layer formed on the active layer, and between the electrode layer and the second conductivity type semiconductor layer.
- a contact metal layer having a thickness equal to or less than a penetration length of light generated in the active layer is formed.
