Subject:        [mems-talk] how to coat a large (40inch*50inch) plate

Dear All,

Now I need to coat photoresisit on a big glass plate
for shot hologram. I try use dip coating way. It is
just like use two big plate make sandwich. then pump
in and pump out photoresist. the bottom 60% looks ok,
but the top 40% have some kind of funny shape. Does
anybody have some idea to coat that large plate.
Thanks!

Paddy
