Abstract:
1. A method for collectively fabricating a reconstituted wafer which comprises chips exhibiting connection pads on a front face of the chips, comprising: positioning the chips on an initial adhesive support, the front face of the chips being on the support, a step of vapor deposition at atmospheric pressure and at ambient temperature, of an electrically insulating mineral layer on the initial support and the chips, said layer having a mechanical role of holding the chips, transferring the chips covered with the electrically insulating mineral layer onto a provisional adhesive support, a rear face of the chips being toward the provisional adhesive support, removing the initial adhesive support, overlaying the chips onto a support of chuck, front faces of the chips toward this support, removing the provisional adhesive support, deposition of a resin on the support of chuck so as to encapsulate the chips, and then polymerization of the resin, removing the support of chuck, producing an RDL layer active face side.
