    摘要: 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.

    摘要: Inventive silsesquioxane polymers are provided, and photoresist compositions that contain such silsesquioxane polymers are provided in which at least a portion of the silsesquioxane polymer contains fluorinated moieties, and at least a portion of the silisesquioxane polymer contains pendant solubility inhibiting cyclic ketal acid-labile moieties that have low activation energy for acid-catalyzed cleaving. The inventive polymer also contains pendant polar moieties that promote alkaline solubility of the resist in aqueous alkaline solutions. The inventive polymers are particularly useful in positive resist compositions. The invention encompasses methods of using such photoresist compositions in forming a patterned structure on a substrate, and particularly multilayer (e.g. bilayer) photolithographic methods, which methods are capable of producing high resolution images at wavelengths such as 193 nm and 157 nm.

    摘要: Acid-catalyzed positive resist compositions suitable for bilayer or multilayer lithographic applications are enabled by the use of a combination of (a) an acid-sensitive imaging polymer, (b) a radiation-sensitive acid generator, and (c) a non-polymeric silicon additive. The imaging polymer is preferably imageable with 193 nm or shorter wavelength imaging radiation. The resist compositions preferably contain at least about 5 wt. % silicon based on the weight of the imaging polymer. The compositions generally provide reduced line edge roughness compared to conventional silicon-containing resists.
