Abstract:
1. Device for connecting at least one nano-object to at least one external electrical system, which device includes: a first level including at least two first electrical contact elements, intended to be connected to the nano-object; a second level including at least two second electrical contact elements, intended to be connected to the external electrical system, in which the second elements have larger dimensions than the dimensions of the first elements; and an intermediate level, located between the first and second levels and making it possible to connect the first elements to the second elements, wherein: the first level also includes a first layer, equipped with the first elements, in which the first elements are electrically insulated from the rest of the first layer; the second level also includes a second layer, equipped with the second elements, in which the second elements are electrically insulated from the rest of the second layer, and a bonding layer, arranged between the second layer and the intermediate level and including at least two electrical through-vias, respectively in contact with the second electrical contact elements; and the intermediate level is intended to connect the vias of the second level with the first electrical contact elements and includes a stack of at least two intermediate layers, respectively equipped with a set of electrically conductive lines that are electrically insulated from the rest of the intermediate layer, and a set of electrical through-vias that are electrically insulated from the rest of the intermediate layer.
