A solid-state device includes a substrate with a stack of constituent thin-film layers that define an arrangement of electrodes and intervening layers. The constituent layers can conform to or follow a non-planar surface of the substrate, thereby providing a 3-D non-planar geometry to the stack. Fabrication employs a common shadow mask moved between lateral positions offset from each other to sequentially form at least some of the layers in the stack, whereby layers with a similar function (e.g., anode, cathode, etc.) can be electrically connected together at respective edge regions. Wiring layers can be coupled to the edge regions for making electrical connection to the respective subset of layers, thereby simplifying the fabrication process. By appropriate selection and deposition of the constituent layers, the multi-layer device can be configured as an energy storage device, an electro-optic device, a sensing device, or any other solid-state device.
