Textured alumina films have been used to fabricate nanoscale pores in Si 3N 4 membranes. A few nanometer-thick alumina layer was used as a masking material for nanopore fabrication, and the pattern was transferred into a 100-nm thick, 200 μm × 200 μm Si 3N 4 membrane by reactive ion etching (RIE). The nanopores were found to be concentrated in a ∼150-μm diameter region at the center of the membrane.
