Residual stress in multilevel interconnects is a potential road block for the ITRS. Direct measurement of stress in interconnect tracks has been demonstrated for the first time using a rotating sensor fabricated in metallisation layers. The rotation is observable with a reflected light microscope and is compared with computer simulations using ANSYS. The structure is suitable for use in a production environment and is scalable to deep submicron features for future technology nodes. (8 References).
