Lithographic patterns

Lithographic patterning of IC features corresponding to those of the physical layout... 

The process of lithographic patterning determines the geometric features specified by the layout and patterning as the integrated circuit is fabricated layer by layer. A photomask, containing pattern information in...

Our initial efforts were directed toward straddling longer molecular wires across lithographically patterned proximal gold-coated probes that were separated by approximately 100 A. Although we tried many experiments over a period of two years, we were never able to record conductances...

The basic procedure for creating addressed aqueous compartments above individual bilayers is outline in Figure 6.6. In the first step, a lithographically patterned PDMS mold is brought into direct contact with a planar supported lipid bilayer containing covalently attached ligands, to create hermetically sealed compartments by microcontact displacement...

The introduction of SAMs on localized areas of a substrate allows straightforward further functionalization and directed assembly of nanoparticles. By using chemistry, specific binding can be introduced, allowing the control of nanoparticle assembly onto lithographic patterns. Wet-chemical self-assembly of nanoparticles is particularly attractive for the fabrication of nanoparticle-based nanostructures because of its compatibility with various kinds of substrates with complex shapes. In this section, conventional and nonconventional patterning techniques for the chemical assembly of nanoparticles will be highlighted.
