Abstract:
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:
The process for manufacturing a micromechanical component made of silicon/metal composite, comprises selectively carving a cavity in an upper layer (5) of a substrate (3) to define a pattern of a silicon part (53) of the component, carving a cavity in an intermediate layer (9) of the substrate, growing a metallic layer from a portion of the cavities (37, 45) to form a metal part along the thickness of the component, and removing the silicon/metal composite micromechanical component from the substrate. The intermediate layer extends between the upper layer and a lower silicon layer (7). The process for manufacturing a micromechanical component made of silicon/metal composite, comprises selectively carving a cavity in an upper layer (5) of a substrate (3) to define a pattern of a silicon part (53) of the component, carving a cavity in an intermediate layer (9) of the substrate, growing a metallic layer from a portion of the cavities (37, 45) to form a metal part along the thickness of the component, and removing the silicon/metal composite micromechanical component from the substrate. The intermediate layer extends between the upper layer and a lower silicon layer (7) of the substrate. The metallic layer is developed by covering the top of the substrate by a photosensitive resin, selectively carrying out a photolithography process on the photosensitive resin according to the predetermined pattern of the metal part, placing a metallic layer in an upper conductive surface of the lower silicon layer by electroplating process, and removing the photostructured resin from the substrate. The upper surface of the lower layer is made conductive by doping the bottom layer and/or by placing a conductive layer on the upper surface. The photostructured resin makes protrusion in the upper layer of the substrate to continue the growth of a layer by electroplating and to prepare a second metal part of the micromechanical component above the silicon part. The upper side of the substrate is made to a level of the metal layer at a height same as the upper end of the photostructured resin, after forming the metal layer. A cavity is carved in the lower layer of the substrate to form a second silicon part of the micromechanical component according to a predetermined form and thickness, before removing the silicon/metal composite micromechanical component from the substrate. An independent claim is included for a micromechanical component made of silicon/metal composite.
