Abstract:
PROBLEM TO BE SOLVED: To form a multi-layer three-dimensional structure on the basis of the electrodeposition of both a structural material and a sacrificial material.SOLUTION: A substrate to be plated 2 is contacted with a first article 4a, which includes a mask 6 and a support 8; a first metal 12 (e.g., a sacrificial metal) is deposited in the presence of a first metal ion source; the substrate 2 is contacted with a second article 14a, which includes a mask 16 and a support 18; a second metal 20 (e.g., a structural metal) is deposited in the presence of a second metal ion source; the layer is planarized; and this method is repeated using differently patterned electroplating articles 4b, 4c, 14b, 14c to produce a multi-layered structure 24, which, after all of the sacrificial metal 12 is etched, becomes an element 26.

PROBLEM TO BE SOLVED: To form a multi-layer three-dimensional structure by electrodepositing both of a structural material and a sacrificial material on a substrate.SOLUTION: A method for manufacturing the multi-layer three-dimensional structure includes the steps of: bringing the substrate 2 to be plated into contact with a first article 4a which includes a mask 6 and a support 8; depositing a first metal 12 (for instance, sacrificial metal) on the substrate in the presence of a first metal ion source; bringing the substrate 2 into contact with a second article 14 which includes a mask 16 and a support 18; depositing a second metal 20 (for instance, structural metal) on the substrate in the presence of a second metal ion source; and planarizing the layer. The method is repeated by using electroplating articles 4a, 4b, 14a and 14b, which have different patterns, to produce a multi-layer structure 24. An element 26 is obtained by etching all of the sacrificial metal 12.
Abstract:
PROBLEM TO BE SOLVED: To provide a composite micromechanical component whose part requiring tribological property is coated with a better tribological material than a micromachinable substrate material, and a method for manufacturing the composite micromechanical component. SOLUTION: The method for manufacturing the composite micromechanical component 41 includes (a) preparing an SOI (silicon on insulator) substrate, (b) etching at least one pattern that penetrates as far as an intermediate layer 22 of the SOI substrate to form at least one cavity in the substrate, (c) coating the outer peripheral part with silicon dioxide having tribological property, and further etching it to form a vertical wall 52 which is the part requiring tribological property, and (d) forming a second level 45 having a level difference in a region that includes the cavity by electroforming.
