Donor substrate micro device stabilization structures and display structures are described. In an embodiment, a patterned electrically conductive layer is used to stabilize an array of micro devices on donor substrate with a plurality of tethers, which can be broken during a transfer sequence to transfer the array of micro devices from the donor substrate.

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.
