  • Patent number: 9536799
    Abstract: The present invention relates to a hot-meltable curable silicone composition for compression molding or laminating and a laminate provided with at least one layer comprising the composition, as well as a semiconductor device using these and a method of manufacturing the same. In accordance with the present invention, it is possible to efficiently manufacture a semiconductor device provided with a hemi-spheroidal lens- or dome-shaped seal. In the present invention, it is easy to control the shape of the seal, and the seal does not contain any bubbles. In the present invention, it is also easy to control the thickness of the coating layer of the semiconductor device apart from the seal.

  • Patent number: 9464211
    Abstract: The present invention relates to a curable silicone composition which is a hydrosilylation reaction curable silicone composition for sealing, coating, or adhering of an optical semiconductor element, and includes at least one type of compound selected from triazole-based compounds with the exception of benzotriazole. The curable silicone composition, for example, includes (A) an organopolysiloxane having at least 2 aliphatic unsaturated hydrocarbon groups per molecule, (B) an organopolysiloxane having at least two silicon-bonded hydrogen atoms per molecule, (C) at least one type of compound selected from among triazole-based compounds with the exception of non-substituted benzotriazole, and (D) a hydrosilylation reaction catalyst. The curable silicone composition forms a cured product having excellent transparency and thermal shock resistance, and the optical semiconductor device utilizing the composition has excellent reliability.

  • Patent number: 8231529
    Abstract: An arm structure includes: a pair of arms; a support post; a support member; a cam provided in one of the pair of arms; a shaft member inserted through a lateral insertion hole of the support member; and a pair of ring-shaped members provided in end portions of the shaft member, wherein by turning the one of the arms around its axis thereby to make the cam revolve, a force works to make the shaft member move, and due to its reaction force the ring-shaped members pressure-contact the support member and a slit portion is narrowed. As a result, a longitudinal insertion hole is diameter-reduced and becomes in a state of pressure-contacting the support post, leading to restriction of rotation of the arm around the support post, and the cam pressure contacts the one of the arms, leading to restriction of sliding of the arm in a long side direction, and the ring-shaped members pressure-contact the support member, leading to restriction of rotation of the arm by the shaft member.
