Abstract:
1. A method for fabricating a micro electromechanical device comprising a first conductor and a second conductor having a collapsible portion that in use is attracted by the first conductor as a result of an RF induced force, the method comprising in combination: locating the first conductor in a plane; and locating the second conductor with at least its collapsible portion at a predetermined distance above the plane, wherein an orthogonal projection of the collapsible portion onto the plane defines a principal actuation area on the plane on which the first conductor extends; wherein the collapsible portion is movable between a distant position further from the principal actuation area and a proximate position closer to the principal actuation area, the movement of the collapsible portion being actuatable by applying an attraction force within the principal actuation area; wherein the collapsible portion shows a variable actuation liability in a longitudinal direction with a region of maximum actuation liability where the attraction force to be applied for actuation is a minimum over the whole principal actuation area; and wherein the first conductor is laterally offset by a predetermined distance from the region of maximum actuation liability, the predetermined distance being used such that a precondition is met, the precondition being a function of the attraction force that in use occurs between the first and second conductors and which the micro-electromechanical device has to be able to withstand.
