Abstract:
1. A method for production of a microelectronic device, comprising: a) producing on a substrate one or more components of at least one electronic circuit, and of one or more metal levels of interconnection of the electronic circuit in at least one insulating layer; b) producing multiple interconnection elements orthogonal to a principal plane of the substrate, traversing the insulating layer, wherein the elements are made from a positive temperature coefficient conductive polymer material; and prior to the producing b), or to the producing a), or to manufacture of the device, determining at least one localized zone of heating of the electronic circuit that can reach a temperature higher than a predetermined threshold when the device is operating within a given current range; and wherein the elements are positioned in the producing b) in accordance with the at least one localized heating zone.
