As top-down fabrication methods like optical lithography are gradually facing their technological and economical limits, alternatives are called for. Bottom-up fabrication methods are still in their early stages of development, but, being based on the self-assembling properties inherent in molecules, they offer much promise for nanocomputers. With expected changes in fabrication method, there will also be changes in the architectures of the resulting computers: it is unlikely that the complicated structures of von Neumann computer architectures can be produced by top-down methods in the nanometer-scale regime. Rather, future computers are expected to ABSTRACT","PeriodicalId":259233,"journal":{"name":"Int. J. Nanotechnol. Mol.
