Abstract
Embodiments include systems and methods for determining a processing parameter of a processing operation. Some embodiments include a diagnostic substrate that comprises a substrate, a circuit layer over the substrate, a capping layer over the circuit layer, and a sensing region across the capping layer. In an embodiment, the sensing region comprises, an array of first micro resonators and a second micro resonator. In an embodiment, the array of first micro resonators surround the second micro resonator.
