Patent ID: 7427526

Claim:
A method for processing a substrate comprising the steps of: depositing a layer of high surface area to volume ratio material having a non-helical columnar structure over a surface of said substrate; removing at least a portion of said high surface area to volume ratio material layer; depositing a stencil layer on said substrate; and patterning said stencil layer and selectively removing a portion of said stencil layer, thereby leaving an exposed portion of said substrate and at least one retained portion of said stencil layer, wherein the step of depositing a layer of high surface area to volume ratio material comprises depositing said high surface area to volume ratio material upon said exposed surface of said substrate and on said at least one retained portion of said stencil layer, further comprising the step of lifting off said stencil layer, thereby also removing a portion of said high surface area to volume ratio material layer deposited thereon.
