摘要:
A protective material for use as an overcoating film for acid catalyzed resist compositions comprising a polymeric film forming compound, the films of which are impermeable to vapors of organic and inorganic bases.
摘要:
A method of synthesizing a silicon-containing positive resist for use as a imaging layer in DUV, x-ray, or e-beam lithography is disclosed. The resist contains arylsilsesquioxane polymers with acid sensitive pendant groups as dissolution inhibitors and a photoacid generator.
摘要:
Positive photoresist compositions and methods using the photoresist compositions for making submicron patterns in the production of semiconductor devices are disclosed. The photoresists contain sensitizers that are mixed naphthoquinonediazide 4- and 5- sulfonic acid esters of bis and tris(mono, di and trihydroxyphenyl) alkanes.
