Abstract:
1. A method for manufacturing contactless portable objects with integrated circuits, comprising the steps of: providing a silicon wafer having integrated circuits including at least one group of two plates with a large surface area for connecting said integrated circuits by capacitive coupling to contact terminals of an antenna conductor circuit provided at the surface of a dielectric substrate of a contactless object, wherein said connection plates are arranged on an active side of said integrated circuits, and wherein a combined surface area of the plates of the at least one group is greater than one-half of a surface area of said active side of the integrated circuits; cutting the integrated circuits from the silicon wafer; grasping the integrated circuits using a gripping means of an integrated circuit transfer machine; and transferring the grasped integrated circuits onto the dielectric substrate so that the plates of said integrated circuits are positioned substantially facing the contact terminals of the antenna conductor circuit, wherein the transferring of the integrated circuits onto the dielectric substrate is carried out with positioning tolerances of 30 microns or more.
