Title:
CURABLE SILICONE COMPOSITION AND OPTICAL SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026755
Kind Code:
A1
Abstract:
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 not having a polyether structure and having at least two hydrogen atoms bonded to a silicon atom in each molecule thereof, (C) a polyether-modified silicone having a siloxane dendron structure and a polyether structure, 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.
