Patterning mask 0 in silica using ASML

Has anyone patterned mask 0 in silica (silicon dioxide) using ASML? I want
to make alignment marks (mask 0) in 300nm silica on silicon substrate. I
plan to evaporate ~100nm silver onto silica and then deposit ~20nm alumina.
I am not sure about the depth of the alignment marks for obtaining best
contrast. I would be extremely grateful for any suggestions/recipe.
