Multilayer photoresist systems |
abstract |
A multilayer photoresist system is provided. In certain aspects, the present invention relates to an undercoat composition for overcoated photoresist, in particular for overcoated silicon-containing photoresist. Preferred underlayer compositions contain one or more resins or other components that impart anti-etching and antireflective properties such as phenyl or other etch resistant groups and other moieties that are antireflective chromophores effective for anthracene or photoresist exposure radiation. At least one resin. |
