摘要:
The present invention provides a composition for forming a bottom anti-reflective coating, and also provides a photoresist pattern formation method employing that composition. The composition gives a bottom anti-reflective coating used in a lithographic process for manufacturing semiconductor devices, and the coating can be developed with a developing solution for photoresist. The composition contains a solvent, a polymer having a condensed polycyclic aromatic group, and a compound having a maleimide derivative or a maleic anhydride derivative. The composition may further contain a photo acid generator or a crosslinking agent.

The present invention provides a fine pattern-forming composition enabling to form a resist pattern having high dry etching resistance, and also provides a pattern formation method using that composition. This formation method hardly causes pipe blockages in the production process. The composition is used for miniaturizing a resist pattern by fattening in a process of forming a negative resist pattern from a chemically amplified resist composition, and comprises a polymer containing a repeating unit having a hydroxyaryl group and an organic solvent not dissolving the negative resist pattern. In the formation method, the fine pattern-forming composition and the resist composition are individually cast with the same coating apparatus, so as to prevent pipe blockages.

A V-ribbed belt 10 includes a bottom rubber layer 12, an adhesive rubber layer 16, and a fabric 22. The bottom rubber layer 12 includes short fibers 14, a part of which protrude from the friction surface 12S of the bottom rubber layer 12. In the bottom rubber layer 12, an FEF carbon black with an average nitrogen adsorption surface area (ASTM D1765-01) of below 49 (m2/g), is used as a reinforcement. Therefore, the friction surface 12S of the bottom rubber layer 12 is slightly uneven, thus preventing the generation of an abnormal noise under usage of the V-ribbed belt 10. Further, after the short fibers 14 protruding from the friction surface 12S of the bottom rubber layer 12 have worn down, the unevenness of the friction surface 12S can be properly maintained by using such a carbon black, so that abnormal noise can be prevented.

The durability of a frictional power transmission belt is improved. A V-ribbed belt (10) comprises an adhesion rubber portion (12) and a compression rubber portion (14) provided below the adhesion rubber portion (12). A cord (11) that is a tension member of the belt is embedded in the adhesion rubber portion (12). The adhesion rubber portion (12) includes an upper layer (12A) constituting the upper side and a lower layer (12B) constituting the lower side, which are located across the cord (11). The upper layer (12A) and the lower layer (12B) are obtained by vulcanizing a rubber composition including a high-viscosity elastomer such as EPM or EPDM, and a low-viscosity elastomer which is lower in Mooney viscosity than the high-viscosity elastomer, and contain modified nylon microfibers as short fibers (21A), (21B), respectively. The short fibers (21A), (21B) are oriented, respectively, in the width direction and longitudinal direction of the belt.
