In this paper, a water-based tungsten-rich micro-lithographic resist consisting of phosphotungstic acid and polyvinyl alcohol (PVA) was used for the subsequent electroless deposition of nickel.Abstract:
Tungsten nuclei, for the subsequent electroless deposition of nickel, were formed of a water-based tungsten-rich microlithographic resist consisting of phosphotungstic acid and polyvinyl alcohol (PVA). Spinning the aqueous resist solution at 4000 RPM yields a pinhole-free 10 3 A thick negative resist film, containing ∼60 weight percent (w/o) tungsten. Exposure (≤100 mJ cm -2 ) of the resists to 254 nm light, postbaking and developing in an aqueous developer produces 0.3 μm featuresread more
