SEMICONDUCTOR LIGHT EMITTING DEVICE

摘要

PURPOSE:To improve the reliability by employing atmospheric gas in a package for gastightly sealing a semiconductor light emitting element gas which contains oxygen, thereby suppressing the deterioration of the element. CONSTITUTION:A heat sink 2 in which a BCLD (Buried Crescent LD) chip 1 is soldered is mounted on a stem 4. Then, a cap 6 is welded to the stem 4 in dry air atmosphere 5. The chip 1 is gastightly sealed in the dry air atmosphere gas in the package. Since the gas 5 is as dry air, the deterioration can be improved without rising a dew point.
