Abstract: A small and thin, light-emitting-element mounting package is provided, in which light emitting elements may by independently controlled despite a side view type package, and a light emitting device using the package is provided. The light-emitting-element mounting package includes a lead frame. The lead frame has at least one set of a structure including a lower conductor layer, an insulating layer and an upper conductor layer in this order, and a mounting area exposed on a surface of the lower conductor layer.

Abstract: A thin film formation apparatus by which source gas is supplied uniformly to the surface of a substrate so that an organic thin film of a uniform film thickness can be formed on the surface of the substrate. The thin film formation apparatus includes a vacuum chamber (11), a substrate holder (12) provided in the vacuum chamber (11), and a gas supplying end element (22) for supplying gas toward a substrate mounting face (12a) of the substrate holder (12). The gas supplying end element (22) is formed so as to supply the source gas in an elongated rectangular shape to the substrate mounting face (12a).

Abstract: A method for forming, without heat evolution, an organic thin film with homogeneous quality on the surface of the substrate. The method consists of vaporizing a single film-forming component of organic material, thereby evolving a film-forming gas (g2), transporting and feeding the film-forming gas (g2) into a reaction chamber (11) in which a substrate (W) is placed, and depositing the organic material, while keeping the film-forming component, on the surface of the substrate (W) in the reaction chamber (11). The substrate (W) is kept cooled while the organic material is being deposited. The film-forming gas (g2) is transported and fed into the reaction chamber (11) by using a carrier gas, such as an inert gas (g1). The deposition of the organic material is repeated so that films differing in composition are formed one over another.

Abstract: A thin-film deposition device for forming an organic thin-film having uniform thickness on a substrate includes a vacuum chamber, a substrate holder provided in the vacuum chamber, and at least one tubular gas supply end that supplies gas towards a substrate mounting-face on the substrate holder. The gas supply end includes therein barriers that control the gas flow in the gas supply end and that are disposed at predetermined intervals toward a gas supply port of the gas supply end. Each of the barriers is provided with a plurality of apertures.

Abstract: The organic raw material is vaporized to generate the raw material gas in the vaporizing chamber. This raw material gas is mixed with the carrier gas, and transported to the chamber through the raw material gas transportation pipe. The substrate is held within the chamber while the organic film formation surface of the substrate does not face downward in a vertical direction straight up from the ground. The injector of the raw material gas is opposed to the substrate. The raw material gas is blasted from the direction orthogonal to the substrate. Particles fall without adhering to the substrate when holding the substrate in the vertical direction. The deformation of the substrate and the mask for separately painting pixels can be suppressed.

Abstract: A first surface of an optical component has a lens function of converging the transmission light from a light source. A second surface reflects the transmission light, converged by the lens function of the first surface, towards an end face of an optical transmission medium as the destination of transmission. The light reflected by the second surface is radaited from a coupling surface. Since the light beam from the light source is directed towards the optical transmission medium by exploiting the total reflection of light, a high-reflection multi-layer film or a polarization beam splitter film, required in a conventional apparatus employing a polarization beam splitter, is unneeded, with the result that the film forming cost or the cost in bonding two prisms used for fabricating the polarization beam splitter may be dispensed with. In this manner, the production cost or size of the apparatus can be reduced without lowering the transmission/reception performance.
