发明名称 PHOTORESIST COMPOSITIONS COMPRISING ACETALS AND KETALS AS SOLVENTS
摘要 <p>Disclosed is a photoresist composition comprising: a) at least one film forming resin selected from the group consisting of novolak resins, and polyhydroxystyrenes; b) at least one photoactive compound or photoacid generator; and c) a solvent composition comprising at least one solvent selected from the group consisting of acetals and ketals. Also disclosed is a photoresist composition comprising a polycarbonate resin and a solvent composition comprising at least one solvent selected from the group consisting of acetals and ketals. Also disclosed is a process for imaging a photoresist composition, comprising the steps of: a) coating a suitable substrate with any of the aforementioned photoresist compositions; b) baking the substrate to substantially remove the solvent; c) imagewise irradiating the photoresist film; and d) removing the imagewise exposed or, alternatively, the unexposed areas of the coated substrate with a suitable developer.</p>
