Abstract: The invention relates to a method for manufacturing a platform for cellular interfacing, the platform being manufactured over a predetermined bulk substrate, the method being a top-down method. According to the invention, such a method comprises the following steps in order: creating (E10) vertical nanowires over the bulk substrate; depositing (E30) a Si layer creating (E40) the access lines for accessing the nanowires; selective silicidation (E50) of the access lines and of the nanowires; metal structuring (E60) of the access lines; depositing (E60) an insulating layer for liquid measurement; selective removal (E70) of the insulating layer on the nanoprobes.

Abstract: A platform for cellular interfacing including at least one nano-probe based on nano-wires each having a conductive extremity intended to be in contact with a cell. The platform has at least one field-effect transistor called a nano-FET positioned at a predetermined distance from the nano-probe.

Abstract: A process for fabricating a field-effect transistor device (20) implemented on a network of vertical nanowires (24), includes: producing a source electrode (26) and a drain electrode (30) at each end of each nanowire (24) symmetrically relative to the gate electrode of each elementary transistor implemented on a nanowire; creating a gate electrode by depositing a layer (38) of conductive material around a layer (36) of dielectric material that surrounds a portion of each nanowire (24), a single conductive layer (38) being used for all of the nanowires and the thickness of the conductive layer corresponding to the gate length of the transistor device; and insulating each electrode with a planar layer (32, 34) of a dielectric material in order to form a nanoscale gate and in order to insulate the contacts of each elementary transistor between the gate and the source and the gate and the drain.
