Abstract
LED donor substrates and conductive architectures for on-wafer testing are described. In an embodiment, an array of LEDs is supported by an array of electrically conductive stabilization posts. The electrically conductive stabilization posts can be coupled with a test pad for on-wafer testing prior to transferring the LEDs to a receiving substrate.
