Embodiments include systems and methods for determining a processing parameter of a processing operation. Embodiments include a diagnostic substrate for determining processing parameters of a processing operation. In an embodiment, the diagnostic substrate comprises a substrate, a circuit layer over the substrate, and a capping layer over the circuit layer. In an embodiment, a micro resonator sensor is in the circuit layer and the capping layer. In an embodiment, the micro resonator sensor comprises, a resonating body and one or more electrodes for inducing resonance in the resonating body.
