Abstract

PURPOSE:To obtain the mask which permits low-cost and highly accurate transfer by forming a supporting frame with the material of a coefficient of linear expansion higher than that of the object to be exposed and the material of a lower coefficient. CONSTITUTION:The supporting frame is formed by combining a ring 21 composed of a material of a coefficient of linear expansion higher than that of the object to be exposed and a ring 22 composed of a material of a smaller coefficient through press-fitting, shrink-fitting, etc. With this constitution, the ring 21 becomes smaller in diameter as compared to the case where it is not a combined ring and the ring 22 becomes larger, when temperature rises. As a result, the apparent coefficient of linear expansion as the combined ring approaches to the coefficient of linear expansion of the object to be exposed, thus the differences in thermal elongation and shrinkage between the mask for X-ray exposure and the object to be exposed are hardly produced.
