Abstract

A method for transferring at least one chip, from a first support to a second support, includes forming, while the chip is assembled to the first support, an interlayer in the liquid state between, and in contact with, a front face of the chip and an assembly surface of a face of the second support and a solidification of the interlayer. Then, the chip is detached from the first support while maintaining the interlayer in the solid state.
