    Abstract: Multi-layer structures are electrochemically fabricated from at least one structural material (e.g. nickel), that is configured to define a desired structure and which may be attached to a substrate, and from at least one sacrificial material (e.g. copper) that surrounds the desired structure. After structure formation, the sacrificial material is removed by a multi-stage etching operation. In some embodiments sacrificial material to be removed may be located within passages or the like on a substrate or within an add-on component. The multi-stage etching operations may be separated by intermediate post processing activities, they may be separated by cleaning operations, or barrier material removal operations, or the like. Barriers may be fixed in position by contact with structural material or with a substrate or they may be solely fixed in position by sacrificial material and are thus free to be removed after all retaining sacrificial material is etched.

    Abstract: Process for fabricating electronic components, of the variable capacitor or microswitch type, comprising a fixed plate (1) and a deformable membrane (20) which are located opposite each other, which comprises the following steps, consisting in: depositing a first metal layer on an oxide layer (2), said first metal layer being intended to form the fixed plate; depositing a metal ribbon (10, 11) on at least part of the periphery and on each side of the fixed plate (1), said ribbon being intended to serve as a spacer between the fixed plate (1) and the deformable membrane (20); depositing a sacrificial resin layer (15) over at least the area of said fixed plate (1); generating, by lithography, a plurality of wells in the surface of said sacrificial resin layer; depositing, by electrolysis, inside the wells formed in the sacrificial resin (15), at least one metal region intended to form the deformable membrane (20), this metal region extending between sections of the metal ribbon (10, 11) which are located on each side of said fixed plate (1); removing the sacrificial resin layer (15).
