UV UV UV CURABLE ADHESIVE SILICONE COMPOSITION UV CURABLE ADHESIVE SILICONE COMPOSITION SHEET OPTICAL SEMICONDUCTOR DEVICE AND METHOD FOR PRODUCING THE SAME

摘要

The present invention relates to an LED chip which can be easily handled because it is in a solid or semi-solid state in a non-cured state at room temperature and is capable of uniformly dispersing the phosphor and covering the surface of the LED chip, A UV curable adhesive silicone composition is provided. Resolution (group R ⁴ is a vinyl or allyl), means _{^{(A) R 1 SiO 3/}} 2, R 2 2 SiO 2/2, R 3 a R 4 b SiO include _{(4-ab) / 2} units, R ^{₂ 2} SiO _^2/2 units is from 5 to 300 resin structure including a mechanism for continuously repeating an _{^{organopolysiloxane, (B) R 1 SiO 3}} /2, R 2 2 SiO 2/2, R 3 c H d SiO a _{(4-cd) / 2} contains the units and R ^{₂ 2} SiO _^2/2 units is 5 organo hydroxy of the resin structure comprising a structure to which 300 continuously repeatedly hydrogen polysiloxane, (C) the vast shaped catalyst , And is a UV curable adhesive silicone composition which is in a solid state or a semi-solid state which is plastic at room temperature in an uncured state.
