摘要： PROBLEM TO BE SOLVED: To improve the light emission extraction efficiency of a light-emitting element in a gallium nitride-based semiconductor light-emitting element. SOLUTION: This gallium nitride-based light-emitting element 100 is provided with a antireflection layer (or a reflecting layer for reflecting light) whose light-transmitting efficiency is made most satisfactory. Also, attenuation of lights radiated to the light radiation side, due to reflection can be suppressed, by an antireflection layer 10, (or lights radiated to the opposite side of the light-extracting side are radiated in a target direction in the reflecting layer). Thus, the lights of the light-emitting element can be more prevented from radiating in surplus directions, and the waste of output can be further prevented, and the light-emitting efficiency can be more improved than in the conventional manner.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a GaN crystal by an Na flux method that increases a crystal growth rate and a growth amount as well as improves uniformity in the thickness of a crystal.SOLUTION: While a GaN crystal is grown by an Na flux method, the distance from the GaN crystal surface in a mixture melt to a gas-liquid interface is kept to 10 mm or less, and a crucible and a seed crystal are independently rotated in the following rotation mode. That is, the rotation direction of the crucible is periodically inverted, so that the rotation direction of the seed crystal is completely opposite to the rotation direction of the crucible. By growing the GaN crystal while rotating the crucible and the seed crystal under the above conditions, the growth rate of the GaN crystal can be raised to increase the growth amount and the GaN crystal can be formed into a uniform thickness.

摘要： PROBLEM TO BE SOLVED: To reduce the stress on an interface between a crystal and a seed crystal when a GaN substrate is obtained by a flux method. SOLUTION: A GaN self-supporting 21 to be used as a seed crystal is produced by a HVPE method using a hetero substrate 1 comprising sapphire. The gallium nitride layer 2 is formed thick by controlling the HVPE conditions in such a manner that the surface 2f of the gallium nitride layer 2 has a less portion to be parallel to the principal plane of the sapphire substrate, and then the hetero substrate 1 is separated (1.A to 1.D). Although the surface 21s is not parallel to the c-plane, the GaN self-supporting 21 functioning as a seed crystal has a planar shape substantially parallel to the c-plane. The GaN self-supporting 21 is conveyed to a flux crystal growth apparatus and a crystal is grown on the surface 21s in a sodium/gallium flux under high temperature and high pressure conditions to form a nitride gallium layer 3 having a layer thickness of 2 mm (1.E). The GaN self-supporting 21 is removed by polishing. The nitride gallium single crystal substrate 31 grown by the flux method is almost free of cracks (1.F). COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a production method of a thick film crystal of a group III nitride compound semiconductor the major face of which is not a c-plane, for fabricating a semiconductor element free from a piezoelectric effect in the layered direction. SOLUTION: The production method of a group III nitride compound semiconductor by a flux method using an alkali metal is disclosed, wherein a group III nitride compound semiconductor substrate 10 having a normal vector of the major face in a direction rotating by 0.2 to 5 degrees from the m-axis toward the +c-axis is used as a seed crystal, on which a crystal growth portion 11 of the group III nitride compound semiconductor is formed by a flux method, thereby a thick film crystal 100 of the group III nitride compound semiconductor having the normal line of the major face in a direction rotating by 0.2 to 5 degrees from the m-axis toward the +c-axis is obtained. Instead of the group III nitride compound semiconductor substrate 10, a group III nitride compound semiconductor film can be used, which has a normal line vector of the major face in a direction rotating by 0.2 to 5 degrees from the m-axis toward the +c-axis direction and is formed on a substrate of a different material.

摘要： PROBLEM TO BE SOLVED: To provide a production apparatus capable of reusing Na, which has been conventionally discarded after the completion of a crystal growth step, in the production of a group III nitride semiconductor by the Na flux method. SOLUTION: After the completion of a crystal growth step of a group III nitride semiconductor by a Na flux method, when the temperature of a crucible 11 is not less than 100°C, Na is sucked by a recovery apparatus 20 and held in a liquid state in a holding container 22. The recovered Na can be taken out from a tap 24. Here, since Na which remains after the completion of a crystal growth step does not contain an impurity with a high vapor pressure, it is highly pure. Thus, if the recovered Na is reused as flux, a group III nitride semiconductor with a low impurity concentration can be produced. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：解决的问题：提供一种能够在通过Na通量法制造III族氮化物半导体时，重新使用在晶体生长步骤完成之后通常被丢弃的Na的制备装置。解决方案：在通过Na通量法完成III族氮化物半导体的晶体生长步骤之后，当坩埚11的温度不低于100℃时，Na被回收装置20吸入并保持在保持容器22中处于液态。回收的Na可以从龙头24中取出。这里，由于在结晶生长步骤结束后残留的Na不含有高蒸气压的杂质，因此高纯。因此，如果回收的Na被重新用作助熔剂，则可以生产具有低杂质浓度的III族氮化物半导体。版权所有（C）2009，JPO＆INPIT
