Method for producing air gaps using nanotubes

摘要

A target layer comprising at least one degradable material is deposited on a support. Nanotubes are then formed on the degradable material of the target layer before deposition of an insulating layer is performed. Degradation of the degradable material and elimination of degradation sub-products are then performed by means of the nanotubes passing through the insulating layer thus forming air gaps in the target layer.
