发光装置
摘要：
一种发光装置(30)，它具备电阻率0.5Ω·cm或其以下的氮化物半导体基板(1)、位于氮化物半导体基板的第1主表面侧的n型氮化物半导体层(3)、从氮化物半导体基板看位于比n型氮化物半导体层(3)更远的位置上的p型氮化物半导体层(5)和位于n型氮化物半导体层(3)以及p型氮化物半导体层(5)之间的发光层(4)；将氮化物半导体基板(1)以及p型氮化物半导体层(5)的任意一方安装在放出光的上侧，另外将另一方安装在下侧，位于该上侧的电极由1个构成。基板通过氧掺杂使之n型化，该氧浓度在氧原子1E17个/cm3～2E19个/cm3的范围内，基板的厚度为100μm～200μm。由此，能够得到可小型化，另外因结构简单而制造容易，可长期稳定地得到较大的发光效率的发光元件。
摘要（英）：

A light emitting device (30) includes a nitride semiconductor substrate (1) with a resistivity of 0.5 OMEGA -cm or less, an n-type nitride semiconductor layer (3) and a p-type nitride semiconductor layer (5) placed more distantly from the nitride semiconductor substrate than the n-type nitride semiconductor layer at a first main surface side of the nitride semiconductor substrate, and a light emitting layer (4) placed between the n-type nitride semiconductor layer (3) and the p-type nitride semiconductor layer (5), wherein one of the nitride semiconductor substrate (1) and the p-type nitride semiconductor layer (5) is mounted at the top side which emits light and the other is placed at the down side, and a single electrode is placed at the top side. Therefore, there is provided a light emitting device which has a simple configuration thereby making it easy to fabricate, can provide a high light emission efficiency for a long time period, and can be easily miniaturized.
