Abstract
A method for making light emitting device LED arrays includes the steps of providing a plurality of LEDs having a desired configuration (e.g., VLED, FCLED, PLED); attaching the LEDs to a carrier substrate and to a temporary substrate; forming one or more metal layers and one or more insulator layers configured to electrically connect the LEDs to form a desired circuitry; and separating the LEDs along with the layered metal layers and insulator layers that form the desired circuitry from the carrier substrate and the temporary substrate.
