Abstract:
Provided are monolithic structures comprising one or more suspended, nanoporous membranes that are in contact with one or more fluidic cavities, methods of making same, and exemplary uses of same. The monolithic structures can be formed using a transmembrane etch. The monolithic structures can be used, as examples, as filters and filtration modules in microfluidic devices, dialysis devices, and concentration devices in laboratory, industrial, and medical processes.

Claim (Index 1):
A method for forming a monolithic structure comprising one or more suspended, nanoporous membranes comprising:\n a) depositing a first membrane material layer on a first side of a substrate; b) depositing a layer of masking material on a second side of the substrate; c) depositing a first pre-patterning layer on the first membrane material layer; d) depositing a first layer of capping material on the first pre-patterning layer; e) forming a first patterning layer by thermal treatment of the substrate that includes the first pre-patterning layer; f) removing the first layer of capping material; g) patterning the first membrane material layer by pattern transfer from the first patterning layer by reactive ion etch; h) optionally, removing the first patterning layer; i) depositing a first layer of via material on the patterned first membrane material layer; j) patterning the first layer of via material such that at least a portion of the patterned first membrane material layer is exposed; and k) patterning the masking material from b), such that at least a portion of the substrate is exposed, removing at least a portion of the substrate by etching with silicon etchants through the patterned first membrane material and the masking material, such that the substrate material corresponding to at least the portion of patterned first membrane material that was exposed is removed and an underlying trench and first suspended, nanoporous membrane are formed, and such that the substrate material corresponding to at least the portion of patterned masking material that was exposed is removed and a fluidic cavity is formed that is fluidically connected to the trench.
