摘要:
A semiconductor-light-emitting-device-mounting member BL comprises (a) a highly heat-dissipative member 1 having a main surface 10 on which connecting-use electrode layers 41 and 42 are provided to form a device-mounting area 10a and (b) a frame-shaped member 2 placed on the main surface 10 so as to surround the device-mounting area 10a. The device-mounting area 10a has an area that is 1.05 to 4 times the area of a semiconductor light-emitting device LE1. A light-emitting-diode-constituting member LE2 mounts a semiconductor light-emitting device LE1 on the device-mounting area 10a of the semiconductor-light-emitting-device-mounting member BL and has a fluorescent body and/or a protective resin LR filling the inside space of the frame-shaped member 2. A light-emitting diode LE3 mounts the light-emitting-diode-constituting member LE2 on a package 7.

摘要:
A semiconductor light-emitting element mounting member with an improved effective light reflectivity in a metal film serving as an electrode layer and/or a reflective layer, in which the metal layer has improved adhesion to a substrate, mechanical strength, and reliability and superior light-emitting characteristics. The semiconductor light-emitting element mounting member (a submount) is made by forming on a substrate metal films formed from Ag, Al, or an alloy containing these metals. The particle diameter of the crystal grains of the metal films is no more than 0.5 μm and the center-line average roughness Ra of the surface is no more than 0.1 μm. In a semiconductor light-emitting device, a semiconductor light-emitting element is mounted in the submount.

A collective substrate has through-holes. The through-holes each have an interior surface including taper surfaces which are tapered as having an opening size progressively decreasing from a main surface and an external connection surface toward a minimum size hole portion. A semiconductor element mount includes an insulative member cut out of the collective substrate. An imaging device includes an imaging element mounted in a region surrounded by a frame which is bonded to the main surface of the insulative member and closed by a cover. A light emitting diode component includes a light emitting element mounted on the main surface of the insulative member with the minimum size hole portion of the through-hole being filled with an electrically conductive material, the light emitting element being sealed with a fluorescent material and/or a protective resin.

A collective substrate (1) is produced by firing a ceramic green sheet and forming through-holes (11) in the resulting substrate. The through-holes (11) each have an interior surface including taper surfaces (11b, 11c) which are tapered as having an opening size progressively decreasing from a main surface (21) and an external connection surface (22) toward a minimum size hole portion (11a). The taper surfaces (11b, 11c) respectively form obtuse angles θ1, θ2 with the main surface (21) and the external connection surface (22). A semiconductor element mount (BL) includes an insulative member (2) cut out of the collective substrate (1). An imaging device (PE2) includes an imaging element (PE1) mounted in a region surrounded by a frame (4) which is bonded to the main surface (21) of the insulative member (2) and closed by a cover (FL). A light emitting diode component (LE2) includes a light emitting element (LE1) mounted on the main surface (21) of the insulative member (2) with the minimum size hole portion (11a) of the through-hole being filled with an electrically conductive material (33a), the light emitting element being sealed with a fluorescent material and/or a protective resin (FR). A light emitting diode (LE3) includes the light emitting diode component (LE2) mounted in a package (7).
