A nonlinear evolution equation for surface-diffusion-driven Asaro-Grinfeld instability of an epitaxially strained thin solid film on a solid substrate was discussed. It was observed that the presence of a weak wetting interaction between the film and the substrate retarded the instability and modified its spectrum. It was observed that unless the wetting potential depended on the slope of the film surface, the spatially regular arrays of dots or pit were subcritical and the solutions of the derived equation blow up in a finite time. Analysis shows that the self-organization dynamics was significantly affected by the presence of the Goldstone mode associated with the conservation of mass.
