Dear Group, I want to find some information on the strength of Silicon Fusion bonds between silicon wafers. In particular I am interested in the strength of the bond in direct tension, in shear, and in bending. Most of the information I can find in the litrature presents information on the surface energy of the bond. Any papers presenting actual fracture strenghts of bonds gives fracture stresses in the range of 5 to 15 MPa. This seems low for an interatomic bond. Any clarifications available?
