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.
Claims23
A process for the selective transfer of elements from a transfer support to a reception support, said elements bonding at a first face to the transfer support with a defined bonding energy, each of said elements having a second face configured to contact said reception support, the process comprising the steps of:
- defining at least one transferring element among said elements, involving separation of said transferring element from the non-transferring elements;
- treating the second face of said transferring element by giving it a bonding energy with said reception support exceeding said bonding energy between its first face and said transfer support;
- retaining said non-transferring elements onto said transfer support;
- configuring said second face of said transferring element to contact with said reception support;
- and
- separating said transfer support from said reception support in order to transfer said transferring element onto said reception support and to retain other of said non-transferring elements on said transfer support.
