Abstract
A method for mounting, on a support, at least a microcircuit in the form of a chip produced on a very thin semiconductor substrate. An interconnection point is provided at the chip in the form of a bump contact in weldable material. The bump contact has a welding surface in the same plane as at least one of the chip faces. An interconnection pad is provided on the support that is designed to be welded with a corresponding bump contact of the chip. The welding face of each bump contact of the chip is placed opposite each corresponding interconnection pad of the support. Each bump contact of the chip is welded with each corresponding interconnection pad of the support. The method can be applied to a device such as a chip card.
