英文摘要：

A calculation model of the thermal stresses in a microstructure fabricated by multilayer thin films was established depending on the processing steps and it was verified by Stoney's equation under the same conditions. Furthermore, it was applied to calculate the deformation of a micro-cantilever fabricated by multilayer thin films under residual stresses. The calculated results were compared with the experimental results to show that their difference is less than 10%. Therefore, the model is applicable and can provide a theory foundation for designing and optimizing of the microstructure fabricated by multilayer films.
