摘要: A method of making an electronic device comprising the steps of: providing a plurality of wafers, each wafer comprising a bonding surface; etching one or more trenches into one or more bonding surfaces, the trenches substantially perpendicular to a preferred direction of diffusion along one or more of the bonding surfaces; rendering the bonding surfaces hydrophobic; and bonding the bonding surfaces together by direct wafer bonding. A semiconductor structure comprising a plurality of wafers, each wafer comprising a bonding surface, one or more bonding surfaces comprising one or more trenches substantially perpendicular to a preferred direction of diffusion along one or more of the bonding surfaces; and the bonding surfaces bonded together by a direct wafer bonding interface.
