    摘要： A process for producing structures in the submicron range is characterized by the following steps:a photoresist layer comprising a polymer constituent with functional groups, which are capable of reacting with primary or secondary amines, and N-blocked imide groups, a photoinitiator which releases an acid when irradiated and a suitable solvent is deposited on to a substrate;the photoresist layer is dried;the photoresist layer is exposed in an imagewise manner;the exposed photoresist layer is subjected to a temperature treatment;the photoresist layer treated in this manner is developed with an aqueous-alkaline or organic developing agent into a photoresist structure; andthe photoresist structure is treated with a chemical agent containing a primary or secondary amine; a defined dark field loss, is adjusted thereby during development in the range of between 20 and 100 nm.

    摘要： The invention provides photosensitive mixtures consisting of a polymer and a photoactive component which meet the requirements placed on photoresists. The polymer has carboxylic acid anhydride groups or phenolic hydroxyl groups and the photoactive component is an N-alkylated or N-arylated 1.4-dihydropyridine or a 1.4- dihydropyridine derivative of the following structure: ##STR1## where the R group is a (substituted) aryl group, which, in the ortho position to the bond with the dihydropyridine ring, carries a NO.sub.2 group; and R.sup.3 is alkyl, cyclohexyl or phenyl.
