Abstract:
(EN) This curable silicone composition is characterized by comprising at least (A) an organopolysiloxane having at least two alkenyl groups in each molecule thereof, (B) an organopolysiloxane having at least two hydrogen atoms bonded to a silicon atom in each molecule thereof, (C) a polyether-modified silicone comprising repeating units represented by the general formula and having a number-average molecular weight of 1000 to 100000, and (D) a hydrosilylation catalyst, the curable silicone composition whereby an optical semiconductor device can be formed having minimal contamination of a case during manufacturing of the optical semiconductor device, good efficiency of light extraction from a light-emitting element, and minimal color unevenness or chromaticity deviation. This optical semiconductor device is also characterized in that a light-emitting element is sealed or covered by a cured material of the composition, and by having minimal contamination of a case, good efficiency of light extraction, and minimal color unevenness or chromaticity deviation.
(FR) L'invention concerne une composition de silicone durcissable, caractérisée en ce qu'elle comprend au moins (A) un organopolysiloxane possédant au moins deux groupes alcényle dans chacune de ses molécules, (B) un organopolysiloxane possédant au moins deux atomes d'hydrogène liés à un atome de silicium dans chacune de ses molécules, (C) une silicone modifiée par polyéther comprenant des unités de répétition représentées par la formule générale et possédant un poids moléculaire moyen en nombre de 1 000 à 100 000, et (D) un catalyseur d'hydrosilylation, la composition de silicone durcissable permettant de former un dispositif optique à semi-conducteurs possédant une contamination minimale d'un boîtier pendant la fabrication du dispositif optique à semi-conducteurs, une efficacité d'extraction de lumière à partir d'un élément électroluminescent satisfaisante et une inégalité de couleur minimale ou un écart de chromaticité minimal. Le dispositif optique à semi-conducteurs est également caractérisé en ce qu'un élément électroluminescent est scellé ou recouvert par un matériau durci de la composition, et en ce qu'il possède une contamination minimale d'un boîtier, une efficacité d'extraction de lumière satisfaisante et une inégalité de couleur minimale ou un écart de chromaticité minimal.
