  • Publication number: 20240136318
    Abstract: A semiconductor device includes a semiconductor element having an Ni—V electrode and a conductor, the semiconductor element and the conductor being bonded via Sn-based lead-free solder. In the semiconductor device, an Sn—V compound layer and an (Ni, Cu)3Sn4 compound layer adjacent to the Sn—V compound are formed adjacent to an interface between the semiconductor element and the Sn-based lead-free solder. A manufacturing method for a semiconductor device according to the present invention includes: causing the Sn-based lead-free solder and the Ni—V electrode to react with each other to form an Sn—V layer and an (Ni, Cu)3Sn4 compound layer; and following formation of the Sn—V layer, leaving an unreacted layer of the Ni—V electrode, the unreacted layer having not reacted with the Sn-based lead-free solder, intact.

  • Patent number: 11955283
    Abstract: A dielectric ceramic composition includes a barium titanate, an oxide of an R element, an oxide of an M element, and an oxide containing Si. The R element is one or more elements selected from Eu, Gd, Tb, Dy, Y, Ho, and Yb. The M element is one or more elements selected from Mg, Ca, Mn, V, and Cr. A ratio of an amount of the oxide of the R element in terms of R2O3 to an amount of the oxide containing Si in terms of SiO2 is 0.8:1 to 2.2:1. A ratio of an amount of the oxide of the M element in terms of MO to the amount of the oxide containing Si in terms of SiO2 is 0.2:1 to 1.8:1.50% or more of the number of dielectric particles constituting the dielectric ceramic composition is core-shell dielectric particles having a core-shell structure.

  • Publication number: 20210100853
    Abstract: An object of the present invention is to provide an agent for decomposing an opioid peptide or composition for decomposing an opioid peptide that does not restrict dietary habits, does not provide side reactions, even if it is daily used, and thus can be continuously used without any worries. The object is achieved by an agent for decomposing an opioid peptide or composition for decomposing an opioid peptide, pharmaceutical composition for decomposing an opioid peptide, or food or drink composition for decomposing an opioid peptide containing a Bifidobacterium bacterium, a culture of the bacterium, and/or a processed cell product of the bacterium as an active ingredient.
