Abstract
Highly sensitive, highly absorbing deep ultraviolet and vacuum ultraviolet resists which comprise a novolak resin protected with an acid labile group and a photoinitiator which generates a strong acid upon exposure to deep ultraviolet or vacuum ultraviolet radiation. The exposed resists are reacted with organometallic compounds to form reactive ion etch resistant patterns.
