    Abstract: The present disclosure relates to an integrated chip having one or more back-end-of-the-line (BEOL) selectivity stress films that apply a stress that improves the performance of semiconductor devices underlying the BEOL selectivity stress films, and an associated method of formation. In some embodiments, the integrated chip has a semiconductor substrate with one or more semiconductor devices having a first device type. A stress transfer element is located within a back-end-of-the-line stack at a position over the one or more semiconductor devices. A selectivity stress film is located over the stress transfer element. The selectivity stress film induces a stress upon the stress transfer element, wherein the stress has a compressive or tensile state depending on the first device type of the one or more semiconductor devices. The stress acts upon the one or more semiconductor devices to improve their performance.
