The method includes the formation of a plurality of posts on at least one of a chip and a wafer, and a like plurality of contacts on the other of the chip and the wafer. After formation, a contact surface of each post is planarized, the respective planarized contact surface having a surface roughness height. A bonding material is then applied to at least one of the chip in a thickness no greater than the surface roughness height of the contact surface.
