Nanomaterials and technology for conductive microstructures

Production of modern microelectronic devices needs printing technologies with the highest level of resolution and repeatability. Ink-jet technology makes it possible to dispense small volumes of a material in the range of tens picolitres. As the results the printed matrix of dots, lines and more complicated shapes have tens to hundreds micrometers scale. The printing of electrically conductive microstructures requires dispensed materials containing conductive particles as a filler. In the paper the systems for printing, possible results as well as background of nano silver production and its properties are presented. Just after ink-jet printing process the structures have the form of molecular fluid without any electrical conductivity hence special technologies for obtaining the printed microstructures with very high conductance have to be applied. As the result it is possible to make lines and complicated shapes with resitivity in range 10^-6 Ohm cm.
