Abstract
An integrated circuit includes a mechanical device for detection of spatial orientation and/or of change in orientation of the integrated circuit. The device is formed in the BEOL and includes an accommodation whose sides include metal portions formed within various metallization levels. A mobile metal component is accommodated within the accommodation. A monitor inside the accommodation defines a displacement area for the metal component and includes electrically conductive elements disposed at the periphery of the displacement area. The component is configured so as to, under the action of the gravity, come into contact with the two electrically conductive elements in response to a given spatial orientation of the integrated circuit. A detector is configured to detect an electrical link passing through the component and the electrically conductive elements.
