Embodiments of the disclosure relate to methods for forming a flat surface MIO structure for bonding and cooling electronic assemblies. In one embodiment, the method includes providing a plurality of particles on a surface of a base substrate. A metal is then deposited onto the plurality of particles up to a desired level to form a metal layer such that the plurality of particles is partially covered by the metal layer. An adhesive member is then applied to the plurality of particles exposed above the metal layer. Finally the adhesive member is pulled to remove individual particles of the plurality of particles that are exposed above the metal layer.
