armnetbooks is ok because it's such a weirdly eclectic and topic-tolerant list.

fosdem mailing list for visitors? mmmm... no.

Are 1um masks that expensive (compared to the rest of setup)? Or is it has more to do with turnaround times?

Can you share details of a light source and resist? One important thing will be to pick light source that will not burn the LCD matrix, and will not be absorbed by the glass much. Making a custom made LCD with special materials might not be that cheaper that sticking with masks for the beginning.

It will be truly great if one can just replace the mask with LCD with no extra work

Hi
My idea was to use an LCD plus a lens system in order to build a mask less
stepper unit for manufacturing semiconductors.
This way the costs for the mask sets would fall away and you would suddenly
be able to provide something like a pooling service for semiconductors.

What do you think?

Something worth combining your brain power over in those said 9 days?

Cheers
