Abstract
Flexible semiconductor devices based on flexible freestanding epitaxial elements are disclosed. The flexible freestanding epitaxial elements provide a virgin as grown epitaxy ready surface for additional growth layers. These flexible semiconductor devices have reduced stress due to the ability to flex with a radius of curvature less than 100 meters. Low radius of curvature flexing enables higher quality epitaxial growth and enables 3D device structures. Uniformity of layer formation is maintained by direct absorption of actinic radiation by the flexible freestanding epitaxial element within a reactor. In addition, standard post processing steps like lithography are enabled by the ability of the devices and elements to be flattened using a secondary support element or vacuum. Finished flexible semiconductor devices can be flexed to a radius of curvature of less than 100 meters. Nitrides, Zinc Oxides, and their alloys are preferred materials for the flexible freestanding epitaxial elements.
