Abstract
A high resolution pattern transfer processes is described, whereby epoxy containing photoresist films are imagewise exposed to radiation, baked to crosslink the exposed areas, and treated with a silylating medium, which reacts with the epoxy ring thereby incorporating silicon at will in the non-crosslinked regions of the film, while making those regions resistant to oxygen atom-containing plasmas.
