G 03 F

 PHOTOMECHANICAL PRODUCTION OF TEXTURED OR PATTERNED SURFACES, e.g. FOR PRINTING, FOR PROCESSING OF SEMICONDUCTOR DEVICES; MATERIALS THEREFOR; ORIGINALS THEREFOR; APPARATUS SPECIALLY ADAPTED THEREFOR (phototypographic composing devices B 41 B; photosensitive materials or processes for photographic purposes G 03 C; electrography, sensitive layers or processes G 03 G)
 

Note
 

In this subclass, the following terms or expressions are used with the meanings indicated:
 

-

 "photosensitive" means not only sensitive of electromagnetic radiation but also to corpuscular radiation;
 

-

 "photosensitive compositions" covers photosensitive substances, e.g. quinonediazides, and, if applicable, binders or additives;
 

-

 "photosensitive materials" covers the photosensitive compositions, e.g. photoresists, the bases carrying them and, if applicable, auxiliary layers. [5]
