Device for connecting nano-objects to external electrical systems, and method for producing the device.According to the invention, which applies in particular to molecular characterization, a device including the following is produced: an upper layer (16) equipped with upper contact pads (8) to be connected to a nano-object (2); a lower layer (18), equipped with lower contact pads (12) to be connected to an external electrical system (4); above the lower layer, a bonding layer (20) including electrical through-vias (22) in contact with the lower pads; and, between the bonding layer and the upper layer, at least two layers (22, 24) equipped with conductive lines (25) and electrical vias (26), for connecting the upper pads to the lower pads.
摘要:
The structure comprises a closed cavity under a controlled atmosphere in which a monoblock getter with a first getter layer is arranged. The first getter layer presents at least first and second getter areas which have different activation temperatures. The second getter area is formed on an adjustment sub-layer of the getter material activation temperature.
摘要:
A method of encapsulating a microelectronic device arranged on a substrate, comprising at least the following steps: a) formation of a portion of sacrificial material covering at least one part of the microelectronic device, the volume of which occupies a space intended to form at least one part of a cavity in which the device is intended to be encapsulated; b) deposition of a layer based on at least one getter material, covering at least one part of the portion of sacrificial material; c) formation of at least one orifice through at least the layer of getter material, forming an access to the portion of sacrificial material; d) elimination of the portion of sacrificial material via the orifice, forming the cavity in which the microelectronic device is encapsulated; and e) sealing of the cavity.
