Abstract
The disclosure relates to a manufacturing method comprising the formation of elemental LED or photovoltaic structures on a first substrate, each comprising at least one p-type layer, an active zone and an n-type layer, formation of a first planar metal layer on the elemental structures, provision of a transfer substrate comprising a second planar metal layer, assembly of the elemental structures with the transfer substrate by bonding of the first and second metal layers by molecular adhesion at room temperature, and removal of the first substrate.
