Abstract
A light-emitting diode (LED) device is provided. The LED device has raised semiconductor regions formed on a substrate. LED structures are formed over the raised semiconductor regions such that bottom contact layers and active layers of the LED device are conformal layers. The top contact layer has a planar surface. In an embodiment, the top contact layers are continuous over a plurality of the raised semiconductor regions while the bottom contact layers and the active layers are discontinuous between adjacent raised semiconductor regions.
