Nanochannel glass replica membranes are thin metallic films containing patterned arrays of uniform, nanometer-scale voids whose sizes, positions, geometric patterns, and packing densities may be controlled to a high degree. These membranes have been prepared from refractory and noble metals and are well suited for use as shadow masks in a variety of substrate patterning applications. Here we describe their use in the sub-micron, parallel patterning of Si and GaAs by materials deposition and reactive-ion etching respectively.
