  电荷转移络合物及蒽与二氧化硫在各种溶剂中的光化学反应

  摘要：

  蒽与二氧化硫的 1:1 电荷转移络合物形成的平衡常数 K 已通过分光光度测量估计在四氯化碳中 15°C 为 0.33。已推导出ΔH (-4.8 kcal.mol-1) 和ΔS° (-19 cal.deg-1mol-1) 的值。在较长波长区域估计时，K 值几乎为零，表明涉及接触电荷转移复合物。在苯中也观察到一种蒽-SO2 的接触电荷转移络合物。已经用在各种溶剂中的二氧化硫用高压汞灯照射蒽。在正己烷、四氯化碳等与二氧化硫无相互作用的溶剂中，蒽生成含硫物质，如蒽-9-磺酸(I)和二蒽基-(9. 9')-磺酸-(10)(II)。相反，在苯或二硫化碳中，不产生磺酸、蒽的二聚体或内过氧化物等产物，...

  A sulfonium salt compound excelling in transparency to deep ultraviolet rays at a wavelength of 220 nm or less, exhibiting well-balanced excellent performance such as sensitivity, resolution, pattern form, LER, and storage stability when used as a photoacid generator, a photoacid generator comprising the sulfonium salt compound, and a positive-tone radiation-sensitive resin composition containing the photoacid generator. The sulfonium salt compound is shown by the following formula (I), wherein R 1 represents a halogen atom, an alkyl group, a monovalent alicyclic hydrocarbon group, an alkoxyl group, or —OR 3 group, wherein R 3 is a monovalent alicyclic hydrocarbon group, R 2 represents a (substituted)-alkyl group or two or more R 2 groups form a cyclic structure, p is 0-7, q is 0-6, n is 0-3, and X − indicates a sulfonic acid anion. The positive-tone radiation-sensitive resin composition comprises (A) a photoacid generator of the sulfonium-salt compound and (B) an acid-dissociable group-containing resin.

• DEVELOPABLE BOTTOM ANTIREFLECTIVE COATING COMPOSITIONS FOR NEGATIVE RESISTS

  A negative developable bottom antireflective coating (NDBARC) material includes a polymer containing an aliphatic alcohol moiety, an aromatic moiety, and a carboxylic acid moiety. The NDBARC composition is insoluble in a typical resist solvent such as propylene glycol methyl ether acetate (PGMEA) after coating and baking. The NDBARC material also includes a photoacid generator, and optionally a crosslinking compound. In the NDBARC material, the carboxylic acid provides the developer solubility, while the alcohol alone, the carboxylic acid alone, or their combination provides the PGMEA resistance. The NDBARC material has resistance to the resist solvent, and thus, intermixing does not occur between NDBARC and resist during resist coating over NDBARC. After exposure and bake, the lithographically exposed portions of both the negative photoresist and the NDBARC layer become insoluble in developer due to the chemically amplified crosslinking of the polymers in negative resist and NDBARC layer in the lithographically exposed portions.

  一种负可展性底部防反射涂层（NDBARC）材料，包括含有脂肪族醇基团、芳香基团和羧酸基团的聚合物。NDBARC组合物在涂覆和烘烤后，不溶于典型的抗蚀剂溶剂，如丙二醇甲醚乙酸酯（PGMEA）。NDBARC材料还包括光酸发生剂，以及可选的交联化合物。在NDBARC材料中，羧酸提供了开发剂的溶解性，而仅有醇，仅有羧酸或它们的组合提供了对PGMEA的抗性。NDBARC材料具有抗抗蚀剂溶剂的性能，因此，在涂覆NDBARC时，NDBARC和抗蚀剂之间不会发生混合。经过曝光和烘烤后，负光刻胶和NDBARC层的光刻曝光部分由于聚合物的化学增强交联而变得不溶于开发剂。

  The present invention relates to a developable bottom antireflective coating (BARC) composition and a pattern forming method using the BARC composition. The BARC composition includes a first polymer having a first carboxylic acid moiety, a hydroxy-containing alicyclic moiety, and a first chromophore moiety; a second polymer having a second carboxylic acid moiety, a hydroxy-containing acyclic moiety, and a second chromophore moiety; a crosslinking agent; and a radiation sensitive acid generator. The first and second chromophore moieties each absorb light at a wavelength from 100 nm to 400 nm. In the patterning forming method, a photoresist layer is formed over a BARC layer of the BARC composition. After exposure, unexposed regions of the photoresist layer and the BARC layer are selectively removed by a developer to form a patterned structure in the photoresist layer. The BARC composition and the pattern forming method are especially useful for implanting levels.

  A fluorescence-based optical sensor includes a membrane immobilized fluorophor secured to one end of a bifurcated fiber optic channel for exposure to the sample to be analyzed. The fiber optic channel also has an input end coupled to a radiation source arranged to supply radiation at two different wavelengths and an output end coupled to a bandwidth limited photosensor. The radiation source alternately excites the fluorophor at a first wavelength that excites an acid form of the fluorophor and at a second wavelength that excites a base form of the fluorophor, and a ratio of the resulting fluorescence intensities is taken as a measure of a characteristic of the sample being analyzed.
