A micro device transfer head and head array are disclosed. In an embodiment, the micro device transfer head includes a base substrate, a mesa structure with sidewalls, an electrode formed over the mesa structure, and a dielectric layer covering the electrode. A voltage can be applied to the micro device transfer head and head array to pick up a micro device from a carrier substrate and release the micro device onto a receiving substrate.
