NICHTPHOTOGRAPHISCHES VERFAHREN ZUR STRUKTURIERUNG ORGANISCHER POLYMERFILME
摘要
A non-photographic method for making patterns in organic polymer films comprising the sequential steps: a. Applying to a substrate an unpatterned first layer comprising a solid organic polymer which is dispersible in a predetermined eluant; b. Applying to the unpatterned first layer a patterned second layer comprising an agent which is capable of changing the dispersibility of the solid organic polymer in the predetermined eluant; c. Effecting patterned diffusion of the dispersibility-changing agent into the underlying solid organic polymer layer; and d. Removing the areas of the underlying solid organic polymer which are dispersible in the eluant by washing them with the predetermined eluant.
