An in situ high-voltage electron microscopic study was made of surface damage-induced dislocation generation and propagation in samples with a periodic mechanical stress-field at the surface. The experimental observations were explained in terms of a theoretical model which described dislocation nucleation as a function of the substrate and stress-field orientations. It was shown that in situ studies of dislocation generation could clarify the basic mechanisms of defect formation in integrated circuits.
