Patent ID: 8011091

Claim:
A fabrication method of a nanotube-based electric connection between first conducting layer and a second conducting layer separated by a target layer, the method successively comprising: forming the target layer on the first conducting layer, forming in the target layer one hole comprising a bottom made by the first conducting layer, growing nanotubes in the hole so as to be in electrical contact with the first conducting layer, the nanotubes comprising porous walls, depositing a flat insulating layer through which the nanotubes pass, decomposing selectively the target layer, made of a decomposable material, the porous walls forming passages between the target layer and an inner part of the nanotubes for a decomposition agent and/or decomposition by-products formed during the selective decomposition, and forming the second conducting layer so as to be electrically connected to the first conducting layer by the nanotubes.
