<p>A positive-working radiation-sensitive coating solution is disclosed which contains a radiation-sensitive compound, e.g., a 1,2-naphthoquinone diazide, or a radiation-sensitive combination of compounds, e.g., a compound with at least one C-O-C bond which can be split by acid and a compound which upon radiation forms a strong acid, and at least one organic solvent which comprises a mono-C1 to C4-alkyl ether of 1,2-propanediol. The coating solution is less toxic and results in a better layer leveling than known positive-working photoresist solutions.</p> |
