First of all Young's modulus for Si can be chosen from
120 to 170. It depends upon many paramters like
deposition rate, temperature, pressure, residual
stresses, intrinsic stresses and thermal stresses and
of course it will be different for different
structures. It also depends upon the stiffness of the
material that you are using for your application. Also
geometry too. So you can see there are so many things
that determine the YOungs' modulus of Si. So you can
select about some value between what I've suggested in
the beginning. Good luck
