摘要： A method for producing a sealed optical semiconductor device includes: placing inner and outermost layer sealing films on a substrate on which an optical semiconductor element is mounted within a pressure reduction chamber, and reducing the pressure; a step in which the outermost film is heated, and at least the periphery of the outermost film is thermally fused to the surface of the substrate; and a step in which the reduction of pressure is released, and the substrate is sealed by the outermost film and the inner film. The temperature T2 of the substrate when the reduction of pressure is released is a temperature at which the outermost film exhibits a tensile strength of 0.02-0.15 MPa and an elongation at break of 200-450%. The inner film exhibits a loss tangent (tan δ) of 1.6 or more at the temperature T2.

摘要： A detergent composition comprises a trisiloxane having at least one carbinol functional group. The trisiloxane comprises the reaction product of (A) an initial trisiloxane and (B) an organic compound. Component (A) has a pendant silicon-bonded functional group selected from a hydrogen atom, an epoxy-containing group, an ethylenically unsaturated group, and an amine group. Typically, component (A) is free of certain terminal silicon-bonded functional groups and is free of polyoxyalkylene groups. Component (B) has a functional group reactive with the pendant silicon-bonded functional group of component (A), and has at least one hydroxyl functional group. The trisiloxane may be of the following general formula (I): (R13SiO1/2)(R1R3SiO2/2)(R13SiO1/2) (I). In formula (I), each R1 is an independently selected hydrocarbyl group. R3 may be selected from the groups (i) to (x) described herein, each of the groups having at least one carbinol group. Typically, the trisiloxane has 1-6 carbinol groups.

摘要： The present invention relates to a curable silicone composition comprising: (A) a diorganopolysiloxane having at least two alkenyl groups in a molecule, (B) at least two types of resinous organopolysiloxanes having different mass average molecular weights, (C) an organopolysiloxane having at least two silicon-bonded hydrogen atoms in a molecule, and (D) a hydrosilylation reaction catalyst. The curable silicone composition enables the production of an optical semiconductor device in which the marked viscosity elevation of the resulting composition can be inhibited, in which the fluidity and packing properties are outstanding and that has outstanding gas barrier properties when used as a sealant, and in which the device has outstanding initial optical output efficiency even when organopolysiloxane resin is blended in order to form cured product with moderate hardness and strength.
