Since Moore’s law was enunciated in 1965, an extreme need arose for the integration of a progressively larger number of transistors per square centimeter. Such a challenge can be accomplished by combining the top-down and the bottom-up approach. In the former, within an attempt to follow this overwhelming demand, photolithography techniques became more and more refined at the expense of fabrication easiness, bulkiness of the machinery and, last but not least, production costs. Furthermore, these top-down fabrication techniques are intrinsically limited by the wavelength of the incident light, nowadays already in the extreme ultraviolet range, as well as the lens quality which will not match up the tens-of-nanometers design rules in the very near future. On the other hand, the bottom-up fabrication requires a deep understanding on the properties of molecular components that nature provided us with, i.e. single molecules or groups of molecules, in particular when interfaced to electrodes.
