However, there are many difficulties in mask fabrications at these wavelengths, the reflective elements of EUV masks being multilayered Bragg mirrors deposited on Si. A synchrotron or plasma source illuminates the mask, the tolerances of the imaging system in the projection exposure method being of only few angstroms. Despite these difficulties, the EUV displays very high yields, including a high speed of feature patterning, of about 1011 features/s. At the extreme end of the electromagnetic spectrum, lithography with X-rays uses high-energy (few keV).

Typical examples are the coaxial Ge/Si and Si/Ge nanowires, obtained by initially growing one nanowire using the VLS method and then applying CVD deposition methods to grow the second nanowire over the first one (Lauhon et al. 2002). Besides growing nanowires with prescribed properties, it is also important to align and position them using self-assembly techniques. Millions of CNTs, for example, can be aligned via a large-scale assembly method similar to biomolecular self-assembly processes (Rao et al.

DNA thin films sandwiched between a n-doped Si substrate and a gold top contact display rectifying characteristics. 78 eV (S¨onmezolu et al. 2010). So, in the case of DNA thin films, the thermionic transport mechanism is dominant, and a Schottky-like diode with good performances can be obtained. We can see from the above examples that there are two basic methods to connect biomolecules to metallic electrodes. One method is the top contact, as in the case of STM tip–(nanoparticle–DNA) electrodes in Fig.
