    摘要: A method for the photolithographic production of structures in the submicron range including the following steps:- a photoresist layer comprising a polymer containing carboxylic acid anhydride and carboxylic acid tert. butyl ester groups, a photoinitiator which releases an acid when exposed, and a suitable solvent is applied to a substrate;- the photoresist layer is dried;- the photoresist layer is exposed in an imagewise manner;- the exposed photoresist layer is subjected to temperature treatment;- the photoresist layer treated in this way is subjected to liquid silylation;- the silylated photoresist layer is dry-developed in an anisotropic oxygen plasma;where the temperature treatment is handled in such a way that the photoresist becomes hydrophilic in the exposed areas.

    摘要: A simple method for diminishing the trench width in a photoresist structure to below the resolution limit is provided. A photoresist structure is produced and treated with an agent then contains a bulging constituent that reacts with functional groups of the photoresist structure. The bulging constituent causes a volume increase of the photoresist structure. The extent of the volume increase of the photoresist structures is controllable by varying various parameters.

    摘要: A photoresist system that is easily structurable and, in particular, is suitable for the deep ultraviolet range is provided. An increased etching resistance to a halogen-containing plasma is produced in a lithographically generated photoresist structure by treatment with a reactant. The reactant comprises predominantly aromatic structures and includes reactive groups that are suitable for chemical reaction with further reactable groups of the photoresist. In an embodiment, the photoresist includes anhydride or epoxy groups that are suitable for structuring with deep ultraviolet light.
