摘要： On a rear surface of a semiconductor (10), a contact layer (11), a diffusion preventing layer (12) and a solder joint layer (13) are formed, and this solder joint layer (13) is connected to a mount base (15) by a Pb-Sn solder layer (14). The contact layer (11) is formed of a rare earth metal, its silicide or a composite thereof, the diffusion preventing layer (12) is formed of a ferrous metal, and the solder joint layer (13) is formed of a Ni-Au alloy. By forming the diffusion preventing layer (12) using the ferrous metal, a diffusion of tin in a solder is prevented and by the solder joint layer (13) of the Ni-Au alloy, an excellent solder joint property can be maintained to reduce the number of laminated layers. Further, as a surface treated layer of at least one joint member, the Ni-Au alloy is used and by heating the semiconductor substrate via a solder foil in a reducing atmosphere a high airtightness is obtained.

摘要： An optical resonator type organic electroluminescent element has a multilayered film mirror 30, a transparent electrode 12, an electron hole transportation layer 14 and a luminescent layer 16 configuring an organic layer, and a metallic electrode mirror 20, formed on a glass substrate 10. The optical resonator type organic electroluminescent element amplifies a specific wavelength (especially, in a range of about 30 nm toward a shorter wavelength side from a luminescence peak wavelength of the organic layer) in luminescence light by a minute optical resonator, which comprises the multilayered film mirror 30 and the metallic electrode mirror 20. It is determined that the minute optical resonator has an optical length L which is twice as long as a resonance wavelength, the organic layer has a thickness of 100 nm or more, and the transparent electrode has a thickness of 50 nm or more or a thickness so to have a sheet resistance of 30 &OHgr;/□ or less. Thus, the transparent electrode can be prevented from generating heat even when a large current is caused to flow into it, and the element characteristics can be reliably prevented from being deteriorated. Moreover, the reliability of this element can be improved because the organic layer containing the luminescent layer has a sufficient thickness.

摘要： 4-Cyanocoumarin derivatives which have a distinct sensitivity to visible light, distinct luminescent ability, and satisfactory applicability for photochemical polymerization, dye lasers, and organic electroluminescent elements. Since most of the derivatives have a fluorescent maximum wavelength of 600 to 650 nm, particularly, 610 to 630 nm, they are extremely useful as luminescent agents for organic EL elements which emit visible light in a red-color region, and can be quite useful as luminescent agents in organic EL elements and laser-active substances in dye lasers, as well as luminous bodies as lighting sources for lighting devices, and information displays for visually displaying information.
