ABSTRACT:
A positive-working photoresist composition comprising a cresol novolac resin as the film-forming agent and a quinonediazido group-containing compound as the photosensitizing agent is admixed with a limited amount of a hydroxyalkyl-substituted pyridine compound so that great improvements can be obtained in the adhesive bonding of the resist layer to the substrate surface and in the stability of the composition by storage still without the problem due to the sublimed material from the resist layer during the patterning process.
