Abstract
A conformable electronic device and methods for forming such devices are described. Embodiments of a conformable electronic device may include a silicon substrate having a thickness of 50 μm or less. An array of LEDs that are electrically coupled to a controller chip may be formed on a surface of the silicon substrate. In an embodiment, a top passivation layer is formed over the array of LEDs, the one or more controller chips, and the top surface of the silicon substrate. An embodiment also includes a bottom passivation layer formed on a bottom surface of the silicon substrate.
