Abstract: PURPOSE:To obtain the micro-pattern on a thin film by a method wherein ion beams are injected into the thin film, which is plasmaetched with a locally transmuted film in the surface layer obtained of the thin film as a mask. CONSTITUTION:An Si3N4 film is deposited on an Si substrate, to which 10<16>- 10<18>cm<-3> of 0 ions at more than 50keV are selectively irradiated. If it is annealed at about 500 deg.C, the part into which the ions have been injected becomes a transmuted layer 7 containing a mixture of SiO2 and Si3N4. Then if the surface layer is plasma- etched by CF4 gas with the layer 7 as a mask, the part that has not been transmuted is selectively removed by etching, and the micro-pattern can be obtained. The transmuted layer 7 is removed, if necessary. With this constitution, the micro- pattern can be readily obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of mislanding even when the ambient temperature is changed by welding the skirt section of a shadow mask main body and the side wall section of a frame at positions near the major axis between the diagonal axes and the major axis, and forming notches weakening the rigidity in the minor axis direction of the frame near the weld points. SOLUTION: A shadow mask main body 29 is made of a small-thermal expansion material such as invar having the thermal expansion coefficient of 1/2 or below that of iron, and a frame 31 is made of an iron material such as a cold rolled steel sheet. When notches 33 are formed on the short side wall sections 30 of the frame 31 near the weld points near the major axis between diagonal axes and the major axis and welded, the rigidity in the minor axis direction of the short side wall sections 30 near the weld points can be weakened. The minor axis direction component of elongation is absorbed by the deformation of the frame 31 near the weld points, and the deformation of the effective face 26 of the shadow mask main body 29 is prevented. When the ambient temperature is increased or decreased, the same effect is obtained, and the deterioration in color purity is prevented.
