Abstract: The invention is for a method and composition for forming one or more patterned layers of functional material over a substrate. The method comprising providing a coating composition comprising a photopatterning material containing a particulate filler of a functional material. The particulate filler is one that is essentially transparent to activating radiation. Once formed, the coating is exposed to activating radiation in an image pattern and developed to form the patterned layer of functional material. The organic components of the coating can be removed if desired.

Abstract: The invention includes use of a positive chemically amplified photoresist composition that produces a strong photogenerated acid. The resist is coated onto a metal substrate that has been subjected to a stringent bake step, e.g. heating of the substrate at about at least 140.degree. C. for more than 60 seconds. The combined use of strong photogenerated acid and stringent pre-coating substrate bake provides highly resolved resist relief images, including on metal substrates.
