THREE-DIMENSIONAL INTEGRATED STRUCTURE COMPRISING AN ANTENNA CROSS REFERENCE TO RELATED APPLICATIONS

摘要

A three-dimensional integrated structure includes a support element, an interface device connected to the support element by a first electrically conductive connection, and an integrated circuit arranged between the support element and the interface device and connected to the interface device by a second electrically conductive connection. A filler region is positioned between the second electrically conductive connection and between the interface device and the integrated circuit. An antenna is distributed over the interface device and the integrated circuit and has a radiating element electromagnetically coupled with an excitation element through the interconnection of a slot.
