Substrates are processed, with a high degree of topography, to produce a variety of semiconductors or other devices and are then stretched out, substantially flat, to achieve a significant increase in surface area. Devices made from a contiguous structure of a single, active crystalline material or from non-contiguous structures of multiple materials, such as a combination of dielectrics, thin film metals and active crystalline semiconductors, are fabricated by utilizing anisotropically etched, high aspect ratio configurations of the active material. The structure is then stretched out to achieve a significant increase in surface area, thereby enabling a substantial reduction in the cost of the substrate materials per unit area in the final product.
