Abstract
A process for the selective transfer of elements from a transfer support to a reception support, the elements bonding through a first face to the transfer support according to a defined bonding energy, the elements each having a second face configured to contact with the reception support. Elements to be transferred are transferred by applying a bonding energy between them and the reception support that exceeds the bonding energy between their first face and the transfer support. Elements not to be transferred onto the transfer support are retained.
