Raman and finite-element analysis of a mechanically strained silicon microstructure.

Bowden, M. and Gardiner, D. J. and Wood, D. and Burdess, J. and Harris, A. and Hedley, J. (2001) 'Raman and finite-element analysis of a mechanically strained silicon microstructure.', Journal of micromechanics and microengineering., 11 (1). pp. 7-12.


Raman microspectroscopy has been used to determine the volumetric micro-strain distribution in mechanically stressed silicon microstructures. Data are presented as strain images with a spatial resolution of around 0.8 µm. A useful correlation is demonstrated between finite-element analysis calculations of volumetric strain and Raman shift. The results demonstrate that silicon beam structures incorporating a 90° bend will experience a non-uniform stress distribution along the bend radius for small radii of curvature.
