Method for transferring objects onto a substrate using a compact particle film, including a step of producing connectors on the objects

A method for transferring objects onto a substrate, comprising:

• providing a transfer area including a carrier liquid forming a conveyor;
• providing a film of particles floating on the carrier liquid;
• placing the objects on the film of particles, the objects displacing a portion of the film of particles;
• forming at least one connector between at least two consecutive objects of the objects placed on the film of particles, the at least one connector being in contact with at least one of said two consecutive objects and comprising a substance including a polymerisable compound, the forming comprising polymerising the substance;
• and
• conveying the objects on the transfer area, the displaced portion of the film of particles keeping the objects on the carrier liquid during the conveying.
