| 1. A method of fabricating a plurality of chips, each chip comprising at least one circuit, which method comprises the following
steps in succession:
creating chips on a layer of semiconductor material that is integral with a substrate;
forming a weakening pattern corresponding to a predetermined cutting pattern on a support;
transferring a layer of semiconductor material that contains the chips from the substrate to the support; and
forming individual chips by cutting the chip-containing layer in accordance with the predetermined cutting pattern.
