This invention provides a new procedure for attaching molecules to semiconductor surfaces, in particular silicon. The molecules, which include, but are not limited to porphyrins and ferrocenes, have been previously shown to be attractive candidates for molecular-based information storage. The new attachment procedure is simple, can be completed in short times, requires minimal amounts of material, is compatible with diverse molecular functional groups, and in some instances affords unprecedented attachment motifs. These features greatly enhance the integration of the molecular materials into the processing steps that are needed to create hybrid molecular/semiconductor information storage devices.

This invention provides a new design and fabrication for a three-dimensional crossbar architecture embedding a sub-micron or nanometer sized hole (called a molehole) in each cross-region. Each molehole is an electrochemical cell consisting of two or more sectional surfaces separated by a non-conductor (e.g. a dialectric layer and solid electrolyte). When used in electrochemical molecular memory device (EMMD), the architecture provides unique features such as a nano-scale electroactive surface, no interaction between memory elements, and easier miniaturization and integration.
