Thin films of nanoscale thickness are common in integrated systems and devices. Subjected to interactions of diverse physical origins, the nanoscale thin films often undergo structural and/or morphological instability and develop a variety of surface patterns. Two examples are discussed in this paper. An epitaxial thin film undergoes surface roughening and form self-assembled quantum dots [1]. A thin metal film bonded to a polymer substrate develops various wrinkle patterns [2]. We develop nonlinear models and numerical methods to simulate the evolution processes. The results reveal very rich dynamics of surface pattern formation and suggest potential means for the control and making of ordered patterns.
