Photo resist is sensitive to U.V. light.  There is about 2% U.V. in
normal white light which makes resist sensitive to white light.  If you
use normal precautions you can expose resist with white light just
expect a long exposure time.  Bill Moffat

Subject: [mems-talk] Photoresist sensitive to visible wavelengths

Hi all,

I am searching for a photoresist that is sensitive to visible wavelength
of light.

especially in 600-800 nm region. I found a conference paper in which
SU-8 3050BW.

a photoresist sensitive to visible range of light, was used. However, I
could not find any information about SU-8 3050BW.

Or is it possible to modify conventional photoresist to be sensitive to
visible spectrum by using photoinitiator and photosensitizer?

Thanks,

Kim, Seung Hoon
