Abstract

Spin-coated films of non-photosensitive engineering thermoplastics mixed with photosensitive agent diazonaphthoquinone (DNQ) can be imaged with near-UV light. The engineering thermoplastics selected for study are commercially available poly(bisphenol A carbonate), polyarylate (U polymer®) and polyetherimide (Ultem®), and synthesized fluorinated polyimide, which have no specific functional groups. Development with a solution including ethanolamine dissolves the irradiated areas to give positive fine patterns. The two-component photosensitive systems showed good photosensitivity and resolution (line/space 10/10 μm) with about 10-15 μm in thickness.
