PROBLEM TO BE SOLVED: To increase the dispersion stability of the glass powder and suppress the occurrence of aggregation of the glass powder with the time by using the glass powder together with a binding resin and fatty acids. SOLUTION: The glass powder preferably softens at 400-600 deg.C and is a mixture of lead oxide, boron oxide and silica or the like. The binding resin is preferably an acrylic resin. Thus, in the resultant membrane-forming material layer manifests excellent adhesion to the glass base material, resultantly the transfer film formed by applying the composition to the substrate film shows excellent transfer to the glass base plate. The amount of the binding resin is 5-40 pts.wt. per 100 pts.wt. of the glass powder. The fatty acid increases the dispersion stability of the glass powder and a saturated fatty acid such as octanoic acid or the like or an unsaturated fatty acid such as elaidic acid or the like can be cited. The content of the fatty acid is preferably 0.001-10 pts.wt. per 100 pts.wt. of the glass powder.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for processing a wafer in which the wafer being processed is held tightly on a substrate and can be stripped easily without breaking the element on the surface when the rear surface of the wafer having semiconductor elements (a fine pattern or holes) on the surface is processed, and a fixing agent layer adhering to the wafer can be removed and/or cleaned easily while eliminating the problem of contaminating the wafer. SOLUTION: After the wafer surface having semiconductor elements is pasted to a substrate using a compound having liquid crystal properties as a wafer fixing agent and heating at a temperature not lower than the melting point of the compound, rear surface provided with no semiconductor element is polished and then the wafer thus heated and polished is removed from the substrate before the wafer fixing agent is cleaned using a solvent.

Abstract:
PROBLEM TO BE SOLVED: To provide a radiation-sensitive composition undergoing a change in refractive index, which can realize a change in the refractive index of a material by a simple method, giving a sufficiently great difference in refractive index due to the change, and can give a refractive index pattern and an optical material that are stable independent of the service conditions thereafter. SOLUTION: The radiation-sensitive composition undergoing a change in refractive index contains (A) a decomposable compound, (B) a nondecomposable compound having a refractive index higher than that of the compound (A), (C) a radiation-sensitive decomposer and (D) a stabilizing agent. The irradiation of the composition with radiations through a pattern mask decomposes the components (C) and (A) at the irradiated part to produce a difference in refractive index between the irradiated part and the unirradiated part, thus forming a pattern different in refractive index.
