| titleOfInvention | Photoresist composition and photoresist material prepared therefrom, containing blocked monomer imide groups, and a suitable maleic-acid monomer |
| abstract | The invention relates to a photoresist mixture and thus produced photoresist material containing a polymer with imide groups which are blocked by methylol or substituted methylol groups bonded to acetal or ketal units, for example the formulas wherein R₀ is hydrogen or methyl R₀ ′ aryl, alkoxy or aryloxy, R₁ and R₂ are hydrogen or (C₁ - C₄) alkyl, R₃ With R₄, R₅ are hydrogen or (C₁ - C₄) alkyl R₆ (C₁ - C₁₀) alkyl R₇ is hydrogen or (C₁ - C₄) alkyl mean, an acid-releasing compound upon exposure which releases the acetal or ketal units by acid formed photolytically at a desired wavelength; and a solvent which dissolves the polymer and acid-releasing compound.n n n The invention also relates to the monomer containing imide groups, such as a maleimide derivative, by means of which the polymer can be prepared as a homo- or copolymer. The polymer can be split off in two stages, 1. when irradiated in the presence of the acid-forming compound and 2. during development, so that finally an alkali-soluble polymer is formed which can be obtained in can remove the irradiated areas.n n n The photoresist material is particularly suitable for DUV radiation and has a high resolving power. |
