    • An acoustically matched reaction resin compound for damping coating of surface wave components is disclosed that contains one or more epoxy resins, one or more dicarboxylic acids or polycarboxylic acids or, respectively, acidic esters of dicarboxylic acids or polycarboxylic acids, an aliphatic or hetero-aromatic amine in a proportion sufficient to catalyze the cross linking of the reaction resin compound, and a solvent. The number of amine hydrogen equivalents and acid equivalents together is less than the number of epoxy equivalents and the uniformly mixed reaction resin compound can be set to a predetermined viscosity and thixotropy required for the application. For example, the reaction resin compound can be applied onto the wafer containing the surface wave components in a silk screening process. Sharp contours can be produced that survive the curing process in an unmodified state. The damping properties of cured reaction resin structures are excellent; corrosion induced by the resin is noticeably reduced.
    • 公开了一种声学匹配的用于阻止表面波分量涂层的反应树脂化合物,其包含一种或多种环氧树脂,一种或多种二羧酸或多元羧酸,或分别为二羧酸或多元羧酸的酸性酯,脂族或杂芳族 胺的比例足以催化反应树脂化合物和溶剂的交联。 胺氢等价物的数量和酸当量一起小于环氧当量的数量,并且可以将均匀混合的反应树脂化合物设定为施加所需的预定粘度和触变性。 例如,反应树脂化合物可以在丝印过程中施加到含有表面波成分的晶片上。 可以产生在未修饰状态下经受固化过程的锋利轮廓。 固化反应树脂结构的阻尼性能优异; 由树脂引起的腐蚀明显降低。

    • A photosensitive resist (100) for coating on a semiconductor substrate or a mask comprises a photo acid generator (D), a solvent (E) and at least two different base polymers, of which a first base polymer comprises cycloaliphatic parent structures (A) which substantially absorb incident light at 248 nm and are substantially transparent to incident light at 193 nm, and a second base polymer comprises aromatic parent structures (B) which substantially absorb incident light at 193 nm and are substantially transparent to incident light at 248 nm. If such a resist (100) is applied in a coat thickness of from 50 to 400 nm to a substrate and the proportion of the second base polymer having the aromatic parent structure is between 1 and 25 mol %, a relatively high structure contrast, better stability to etching and a reduction of defects are advantageously achieved in an exposure at a wavelength of 193 nm. Exposure over the entire depth range of the resist (100) is ensured thereby.
    • 用于在半导体衬底或掩模上涂覆的光敏抗蚀剂(100)包括光酸产生剂(D),溶剂(E)和至少两种不同的基础聚合物,其中第一种基础聚合物包含脂环族母体结构(A) 其基本上吸收在248nm处的入射光并且对193nm的入射光基本上是透明的,并且第二基础聚合物包括基本上吸收193nm的入射光并对248nm的入射光基本透明的芳族母体结构(B)。 如果将这样的抗蚀剂(100)以50-400nm的涂层厚度施加到基材上,并且具有芳族母体结构的第二基础聚合物的比例在1至25摩尔%之间,则相对较高的结构对比度 在193nm的波长的曝光中有利地实现了蚀刻的稳定性和缺陷的减少。 从而确保抗蚀剂(100)的整个深度范围的曝光。
