Patent ID: 7713871

Claim:
A process of manufacturing a system for contacting at least one electronic device having a plurality of contact elements, the process including the steps of: providing a substrate having a main surface, and forming a plurality of contact terminals projecting from the main surface, wherein each contact terminal includes a core and a covering of conductive material surrounding the core, the covering having an operative portion spaced apart from the main surface for electrically connecting a corresponding contact element and a lateral portion extending between the main surface and the operative portion, wherein the lateral portion forms an angle with the main surface between 45° and 75°; wherein the step of forming the contact terminals includes: providing a sacrificial structure having a substantially flat exposed surface, the sacrificial structure including a wafer of semiconductor material having a working surface corresponding to the exposed surface, selectively etching the sacrificial structure to form a plurality of grooves on the exposed surface corresponding to the contact terminals, depositing at least one first metallic layer on the exposed surface of the sacrificial structure, filling the grooves with the polymeric material, depositing at least one second metallic layer on the at least one first metallic layer to obtain a structure including the contact terminals, associating the structure with the substrate, and removing the sacrificial structure.
