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.

Conductive micro LED architecture for on-wafer testing

Laser lift-off methods are described in which optical flatness is provided on the back side of a temporary substrate using either an optical layer or optical liquid. A laser is directed through the optical layer or optical liquid and a back side of the temporary substrate to decompose a portion of a process layer supported on a front side of the temporary substrate, followed by separation of the process layer and the temporary substrate.
