DRIE uniformity vs residual stress

Hi All, Has anyone any references on DRIE etch uniformity sensitivity to residual stress? Particularly the Bosch process. I know I have heard that Si etches less uniformly if it is stressed, kinda like stress corrosion, the bonds are easier to break if they are stretched so higher stress is higher etch rate. thanks, Matthew
