    摘要: A molecular resist composition and method of use is disclosed wherein the composition includes no silicon containing material, no polymeric material, and a substituted oligosaccharide, wherein the substituted oligosaccharide is substituted with at least one acid-cleavable —OR group, wherein the substituted oligosaccharide has 2 to 10 monosaccharides, wherein the molecular resist may be initially insoluble in developer, which may be an aqueous alkaline solution or developer consisting essentially of water. In some embodiments, the molecular resist may become soluble in the developer consisting essentially of water upon exposure to radiation having a wavelength of 193 nm or less and a post-exposure bake temperature from about room temperature to about 110° C. The resist material of the present invention may be used to print feature sizes wherein developed images may have a line/spacing not greater than than 120 nm when the developer consists essentially of water or an aqueous alkaline solution.

    摘要: A nonpolymeric silsesquioxane is provided wherein at least one silicon atom of the silsesquioxane is directly or indirectly bound to an acid-cleavable substituent RCL. The silsesquioxane has a glass transition temperature Tg of greater than 50° C, and the RCL substituent can be cleaved from the silsesquioxane at a temperature below Tg, generally at least 5° C. below Tg. The remainder of the silicon atoms within the silsesquioxane structure may be bound to additional acid-cleavable groups, acid-inert polar groups RP, and/or acid-inert nonpolar groups RNP. The nonpolymeric silsesquioxane can be a polyhedral silsesquioxane optionally having one to three open vertices, such that the polyhedron appears to be a “partial cage” structure, or a macromer of two to four such polyhedral silsesquioxanes. Photoresist compositions containing the novel nonpolymeric silsesquioxanes are also provided, as is a method for using the compositions in preparing a patterned substrate.
