Title (EN) INVERTED LED STRUCTURE WITH IMPROVED LIGHT EXTRACTION
(FR) STRUCTURE À LED INVERSÉE MUNIE D’UNE EXTRACTION DE LUMIÈRE AMÉLIORÉE
Abstract: front page image
(EN)A light source[30] and method for fabricating the same are disclosed. The light source[30] includes a substrate and a light emitting structure. The substrate[24] has a first surface and a second surface, the second surface including a curved, convex surface[39] with respect to the first surface of the substrate. The light emitting structure includes a first layer[21] of a material of a first conductivity type overlying the first surface, an active layer [22] overlying the first layer, the active layer generating light when holes and electrons recombine therein, and a second layer[23] includes a material of a second conductivity type overlying the active layer and a second surface opposite to the first surface. A mirror layer[25] overlies the light emitting structure.
(FR)La présente invention concerne une source de lumière (30) et un procédé pour sa fabrication. La source de lumière (30) comprend un substrat et une structure électroluminescente. Le substrat (24) comporte une première surface et une seconde surface, la seconde surface incluant une surface convexe courbée (39) par rapport à la première surface du substrat. La structure électroluminescente comprend une première couche (21) d’un matériau d’un premier type de conductivité recouvrant la première surface, une couche active (22) recouvrant la première couche, la couche active générant de la lumière lorsque des trous et des électrons se recombinent dans celle-ci, et une seconde couche (23) incluant un matériau d’un second type de conductivité recouvrant la couche active et une seconde surface opposée à la première surface. Une couche miroir (25) recouvre la structure électroluminescente.
