In this paper, a linearized energy-stable Galerkin scheme is investigated for a semilinear wave equation. Based on the special property of the bilinear element on the rectangular mesh, the superconvergence error estimate in is obtained in terms of a suitable post-processing approach. Finally, a numerical example is presented to support the theoretical analysis.
