We present an ion-lattice quantum processor based on a two-dimensional arrangement of linear surface traps. Our design features a tunable coupling between ions in adjacent lattice sites and a configurable ion-lattice connectivity, allowing one, e. g., to realize square and triangular lattices with the same trap chip. We present detailed trap simulations of a simplest-instance ion array with 2x9 trapping sites and report on the fabrication of a prototype device in an industrial facility. The design and the employed fabrication processes are scalable to larger array sizes. We demonstrate trapping of ions in square and triangular lattices and demonstrate transport of a 2x2 ion-lattice over one lattice period.
