Abstract:
A method for manufacturing a nanotube non-volatile memory cell ( 100 ) is proposed. The method includes the steps of: forming a source electrode ( 110 ) and a drain electrode ( 115 ), forming a nanotube ( 125 ) implementing a conduction channel between the source electrode and the drain electrode, forming an insulated floating gate ( 130 ) for storing electric charges by passivating conductive nanoparticles with passivation molecules and arranging a disposition of passivated conductive nanoparticles on the nanotube, the conductive nanoparticles being adapted to store the electric charges and being insulated by the passivation molecules from the nanotube, and forming a control gate ( 135,150;335 ) coupled with the channel.
Abstract:
Method for realising a sensor device (20) suitable for detecting the presence of chemical substances and comprising, as detection element, an active film (24) of metallic nanoparticles able to interact with the chemical substances to determine a variation of the global electric conductivity of the film (24). The method comprises the steps of preparing an ink comprising a solution of metallic nanoparticles, and depositing the obtained ink on a supporting substrate (26) by means of ink-jet printing so as to form the active film (24).
