摘要： A thin-film EL display device of red luminescent color having high luminous intensity and high reliability is disclosed. The thin-film EL display device has a first transparent electrode, a first transparent insulating layer, a light-emitting layer of zinc sulfide (ZnS) with the addition of manganese (Mn), a red-light transmitting filter of amorphous silicon (a-Si), a second transparent insulating layer, and a second transparent electrode (second electrode), which are successively deposited one on top of another on a glass substrate. The EL display device produces red light from orange light emission from the light-emitting layer. High temperature resistance of the filter permits the insertion of the filter to a desired position during the fabrication process for the thin-film EL display device. Furthermore, since the filter characteristics of the thin-film EL display do not suffer degradation by the heat generated during the light emitting operation thereof, there is no concern for luminescent color deterioration with time.

A first gaseous source material of a group II element belonging to group II of the periodic table, a second gaseous source material of a group VIB element belonging to group VIB, and a third gaseous source material of an element forming the luminescent center of the luminescent layer are supplied into a reaction furnace through first, second, and third gas supply tubes, respectively, and caused to react with each other. Thus, the luminescent layer is formed by chemical vapor deposition. The first material acts as a base material from which the luminescent layer is formed. The first tube for the first material is laid in the center of the furnace. The third tube for the third material forming the luminescent center is laid around the first gas supply tube. The second tube is laid around the third tube.

摘要： A dry etching method performing dry etching of a material containing zinc forms and patterns a resist on the material to be etched, and etches the material using an etching gas which is a mixed gas of methane gas and an inert gas. A dry etching method that dry etches a material containing zinc etches the material using an etching gas that consists only of methane gas, an inert gas, and hydrogen gas alone. Another dry etching method that dry etches a material containing zinc introduces an etching gas that contains methane gas, an inert gas, and hydrogen gas into a dry etching device, in which the flow rate of the hydrogen gas is set such that it is equal to or greater than the value at which the amount of dissociated hydrogen becomes saturated, and etches the material using the etching gas. An EL element manufacturing method forms a first luminescent material containing zinc in its composition on a first insulated layer, forms a first resist that has a first pattern on the first luminescent material, dry etches the first luminescent material through the first resist, thereby forming the first luminescent layer; forms a second luminescent material having zinc in its composition on the first luminescent layer, forms a second resist on the second luminescent material, and dry etches the second luminescent material through the second resist.
