Patterning process
21 Jun 22
A patterning process, including: forming the first resist film from first resist material containing an acid generator and thermosetting compound having a hydroxy group and/or carboxy group protected by an acid-labile group; forming the second resist film on first resist film from a second resist material containing a metal compound (A) and a sensitizer; irradiating the first and second resist film with a high energy beam or an electron beam to perform pattern exposure to deprotect the hydroxy group and/or carboxy group in a pattern exposed portion of first resist film and to form a crosslinked portion of the component (A) with the deprotected hydroxy and/or carboxy group on the pattern exposed portion; and developing the second resist film with a developer to give a metal film pattern composed of the crosslinked portion.
