发明名称 Electrochemical fabrication methods for producing multilayer structures including the use of diamond machining in the planarization of deposits of material
摘要 Electrochemical fabrication methods for forming single and multilayer mesoscale and microscale structures are disclosed which include the use of diamond machining (e.g. fly cutting or turning) to planarize layers. Some embodiments focus on systems of sacrificial and structural materials which are useful in Electrochemical fabrication and which can be diamond machined with minimal tool wear (e.g. Ni-P and Cu, Au and Cu, Cu and Sn, Au and Cu, Au and Sn, and Au and Sn-Pb), where the first material or materials are the structural materials and the second is the sacrificial material). Some embodiments focus on methods for reducing tool wear when using diamond machining to planarize structures being electrochemically fabricated using difficult-to-machine materials (e.g. by depositing difficult to machine material selectively and potentially with little excess plating thickness, and/or pre-machining depositions to within a small increment of desired surface level (e.g. using lapping or a rough cutting operation) and then using diamond fly cutting to complete he process, and/or forming structures or portions of structures from thin walled regions of hard-to-machine material as opposed to wide solid regions of structural material.
