DEVICE AND METHOD FOR MANUFACTURING DEVICES COMPRISING AT LEAST ONE CHIP MOUNTED ON A SUPPORT

摘要

The invention concerns a method for making a device comprising a support (2) associated with at least a microcircuit in the form of a chip (6), for example a chip card. The invention is characterised in that it comprises, for the or each chip, steps which consist in: first providing for said chip an assembly consisting of a thin chip (6) maintained by a first surface (6b) integral with a substrate (8) and having on an opposite second surface (6a) at least a bond pad (12); forming, on a surface (2a) of the support a communication interface (4) comprising at least a connecting element (4b) with said chip; then, successively: placing said assembly comprising the chip (6) and the substrate (8) against the communication interface, with at least a bond pad (12) of the chip positioned against a corresponding connection element (4b; 24a, 24b) of the communication interface; integrating the or each pad with its respective connection element; and removing said substrate (8) from said first surface (6b) of the chip. The method advantageously uses the SOI chip technology.
