Title (EN) NITRIDE SEMICONDUCTOR LIGHT-EMITTING DEVICE
(FR) DISPOSITIF ÉLECTROLUMINESCENT À SEMI-CONDUCTEUR AU NITRURE
(JA) 窒化物半導体発光装置
Abstract: front page image
(EN)Disclosed is a nitride semiconductor light-emitting device comprising a substrate (101) composed of silicon; a mask film (102) composed of silicon oxide, which film is formed on a major surface of the substrate (101) and has at least one opening (102a); a seed layer (104) composed of GaN and selectively formed on the substrate (101) in the opening (102a); an LEG layer (105) formed on the lateral surface of the seed layer (104); and an n-type GaN layer (106) including an active layer (107) and a p-type GaN layer (108) formed on the LEG layer (105). In this connection, the LEG layer is formed by crystal growth using an organic nitrogen material as a nitrogen source.
(FR)L'invention porte sur un dispositif électroluminescent à semi-conducteur au nitrure comprenant un substrat (101) composé de silicium ; un film de masque (102) composé d'oxyde de silicium, lequel film est formé sur une surface principale du substrat (101) et comporte au moins une ouverture (102a) ; une couche de germe (104) composée de GaN et sélectivement formée sur le substrat (101) dans l'ouverture (102a) ; une couche LEG (105) formée sur la surface latérale de la couche de germe (104) ; et une couche GaN de type n (106) comprenant une couche active (107) et une couche GaN de type p (108) formée sur la couche LEG (105). A cet égard, la couche LEG est formée par croissance cristalline en utilisant un matériau azoté organique en tant que source d'azote.
(JA) シリコンからなる基板(101)と、基板(101)の主面上に形成され、少なくとも1つの開口部(102a)を有する酸化シリコンからなるマスク膜(102)と、基板(101)における開口部(102a)の上に選択的に形成されたGaNからなるシード層(104)と、シード層(104)の側面に形成されたLEG層(105)と、LEG層(105)の上に形成され、活性層(107)を含むn型GaN層(106)及びp型GaN層(108)とを有している。ここで、LEG層(105)は、窒素源に有機窒素原料を用いた結晶成長により形成されている。
