SEMICONDUCTOR LIGHT EMITTING DEVICE COMPRISING UNEVEN SUBSTRATE |
| 摘要 |
At least one depression (20) and/or projection (21) for scattering or diffracting light generated in a light emitting region (12) is formed in the surface of a substrate (10). The recess and/or projection is so shaped as to generate no crystal defects in semiconductor layers (11, 13). |
