Abstract: A shadow mask is applicable to forming a minute film on a substrate by evaporation or the like. The shadow mask comprises a support film, a stopper film, a polyimide film and a thin plate. The support film has enough mechanical strength necessary for forming predetermined sized holes. The stopper film is formed on the support film and is used as an etching stopper while forming the holes in the support film. The polyimide film is formed on the stopper film and bonds the stopper film to the thin plate. The thin plate is formed on the polyimide film and is made of a material which is the same as that of the substrate on which the film is formed or a material whose thermal expansion rate is substantially the same as that of the substrate. Openings of the shadow mask are formed at predetermined regions through the support film, the stopper film, the polyimide film and the thin plate. Each of the openings has a tapered portion and a projected portion.

Abstract: A positive hole transporting layer (14) is formed on an ITO film so as to form a substrate (10). A light emission organic material (20) is formed on the front surface of a convex protrusion portion (18) of a metal sheet (16). The front surface of the positive hole transporting layer (14) and the convex protrusion portion (18) are clamped with a glass plate (22). Laser light is radiated to the interior of the convex protrusion portion (18) through a shielding plate with an opening portion whose size corresponds to the size of the convex protrusion portion (18). The light emission organic material formed on the front surface of the convex protrusion portion (18) sublimates and transfers to the positive hole transporting layer (14). These steps are performed for areas of three color light emission devices.

Abstract: KrF excimer laser beam is selectively irradiated to a resist film. At this time, an incident light (KrF excimer laser beam) is reflected at the surface of an antireflection film to be a first reflected light, and is reflected at the surface of a film to be patterned to be a second reflected light. A standing wave is obtained by interference between the incident light and the first and the second reflected light. A light intensity of this standing wave has extreme maximum and extreme minimum appearing alternately, and a pair of extreme minimum and extreme maximum is across the first interface. A reflection index of the first reflected light is a range of 10 to 20%. Also, the thickness of the antireflection film is adjusted so that the extreme maximum of the pair is located in the resist film and the extreme minimum of the pair is located in the antireflection film.
