Light-emitting diode with embedded elements

摘要

A light-emitting diode (LED) device is provided. The LED device has a substrate and an LED structure overlying the substrate. Embedded elements are embedded within one or more layers of the LED structure. In an embodiment, the embedded elements include a dielectric material extending through the LED structure such that the embedded elements are surrounded by the LED structure. In another embodiment, the embedded elements only extend through an upper layer of the LED structure, or alternatively, partially through the upper layer of the LED structure. Another conductive layer may be formed over the upper layer of the LED structure and the embedded elements.
