Title:
CURABLE POLYBOROSILOXANE RESIN COMPOSITION, CURED OBJECT OBTAINED TEHREFROM, AND OPTICAL SEMICONDUCTOR DEVICE OBTAINED USING SAID COMPOSITION OR INCLUDING SAID CURED OBJECT
Document Type and Number:
WIPO Patent Application WO/2017/010327
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a curable polyborosiloxane resin composition which not only gives a cured object excellent in terms of tight adhesion to the package substrate and heat resistance concerning transparency but also has excellent storage stability; a cured object obtained from the composition; and an optical semiconductor device obtained using the composition or including the cured object. The curable polyborosiloxane resin composition according to the present invention comprises a given polyborosiloxane resin having hydrosilyl groups as component (A), a given silicone resin having vinyl groups as component (B), and a hydrosilylation catalyst as component (C). The composition not only gives a cured object excellent in terms of tight adhesion to the package substrate and heat resistance concerning transparency but also has excellent storage stability. The cured object is suitable for use in optical semiconductor devices as the encapsulating material for the optical semiconductor elements.
