△ [19a-E304-8] Measurement of Stress Distribution in Thin Film Mechanical Resonator by Micro-Raman Spectroscopy
Keywords:NEMS, stress, Micro-Raman Spectroscopy
Stress occurs in a thin film mechanical resonator which is a component of NEMS. Raman spectroscopy is one of the methods to measure stress, but its applicability to a thin film has not been clear. In this study, we modeled mechanism of spectrum formation when Raman spectroscopy is applied to a thin film which has stress distribution inside and proposed a method to quantify the stress distribution in a thin film.
