Summary: | Negative relief images are generated by a process comprising the use of cationic polymerization and plasma etching. The process comprises a process for generating a negative tone resist image comprising the steps of:(1) coating a substrate with a film that contains a cationic photoinitiator;(2) exposing the film in an imagewise fashion to radiation and thereby generating cationic initiator in the exposed regions of the film;(3) treating the exposed film with a cationic-sensitive monomer to form a film of polymer resistant to plasma etching; and(4) developing the resist image by etching with a plasma. |
