This talk is devoted to a $\theta$-$L$ numerical method for solid-state dewetting of thin films. Solid-state dewetting belongs to a class of interface problems and the motion of the (film/vapor) interface is governed by surface diffusion and contact line migration. We first briefly review several methods for solving its sharp-interface model, including the "Marker-particle" method and the parametric finite element method. Then we propose a new $\theta$-$L$ approach which can both reduce the stiffness from surface diffusion and improve the performance in mesh distribution. This is a joint work with Prof. Wei Jiang and Prof. Yan Wang.
