Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an electronic micro component with a fixed plate and a deformable film facing each other under a room temperature. SOLUTION: This manufacturing method is characterized in having a stage of depositing a first metal layer to become the fixed plate on an oxide layer 2, a stage of depositing metal ribbons 10 and 11 acting as spacers between the fixed plate 1 and the deformable film 20 at least in a part of the circumferential edge of the fixed plate 1 in its both sides, a stage of depositing a sacrifice resin layer 15 on all over the fixed plate; a stage of forming a plurality of wells on the surface of the sacrifice resin layer by lithography, a stage of depositing, at least, a metal region which forms the deformable film 20 in the wells formed on the sacrifice resin layer 15 and extends between the metal ribbons disposed in both sides of the fixed plate; and a stage of removing the sacrifice layer.

Abstract: PROBLEM TO BE SOLVED: To provide a microelectric element, such as the microinductor, microtransformer, etc., having a satisfactory Q-factor or a large self-inductance value. SOLUTION: In a method for manufacturing a microelectric element, channels are formed in a substrate 1 by etching and copper segments 7 are formed in the channels. Then the upper surfaces of the segments 7 and the upper surface of the substrate 1 are made even, and at least one layer constituting a core is formed on the upper surfaces of the substrate 1 and the segments 7. Thereafter, the core is etched so that the core may be left only on bands and a plurality of arches 18 each of which couples one end of a certain segment 7, with one end of its adjacent segment 7 over the core being electrolytically grown astride over the core.

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).

Abstract: The microcomponent manufacture technique has a substrate etched with a number of channels. Copper is deposited by electrolys in the channels and planed flat. A central section (12) is deposited above the segments (7). The central section is then etched for arch sections, each arc connected to an adjacent segment and forming a spiral winding.
