A method for producing a component, comprising: producing a first layer composite, which comprises a structured layer, which is electrically conductive at least in a first region, and a trench filled with an insulating material, which extends from a first surface of the structured layer and is arranged in the first region of the structured layer, the first surface of the structured layer facing a first surface of the first layer composite, producing a second layer composite, which has a first depression in a first surface of the second layer composite, connecting the first layer composite to the second layer composite, the first surface of the first layer composite adjoining the first surface of the second layer composite at least in some regions, and said filled trench being arranged within the lateral position of the first depression, after the first layer composite has been connected to the second layer composite, the thickness of the first layer composite is reduced starting from a second surface of the first layer composite to the depth of the filled trench, the second surface of the first layer composite lying opposite the first surface of the first layer composite, producing an active structure of the component in the structured layer, said active structure being arranged within the lateral position of the first depression and comprising two second regions of the structured layer, which are arranged in the first region of the structured layer, are physically connected to each other in a rigid manner, and are electrically insulated from each other by means of the filled trench, prior to connecting the first layer composite to the second layer composite, the filled trench in the first layer composite extends to a depth (d 15), which is smaller than a thickness (d 10) of the first layer composite, characterized in that the first layer composite further comprises an auxiliary layer different from the structured layer, which adheres well to the structured layer, can be removed again, and adjoins a second surface of the structured layer, with the second surface of the structured layer lying opposite the first surface of the structured layer, and the filled trench extends to the second surface of the structured layer. producing a first layer composite, which comprises a structured layer, which is electrically conductive at least in a first region, and a trench filled with an insulating material, which extends from a first surface of the structured layer and is arranged in the first region of the structured layer, the first surface of the structured layer facing a first surface of the first layer composite, producing a second layer composite, which has a first depression in a first surface of the second layer composite, connecting the first layer composite to the second layer composite, the first surface of the first layer composite adjoining the first surface of the second layer composite at least in some regions, and said filled trench being arranged within the lateral position of the first depression, after the first layer composite has been connected to the second layer composite, the thickness of the first layer composite is reduced starting from a second surface of the first layer composite to the depth of the filled trench, the second surface of the first layer composite lying opposite the first surface of the first layer composite, producing an active structure of the component in the structured layer, said active structure being arranged within the lateral position of the first depression and comprising two second regions of the structured layer, which are arranged in the first region of the structured layer, are physically connected to each other in a rigid manner, and are electrically insulated from each other by means of the filled trench, prior to connecting the first layer composite to the second layer composite, the filled trench in the first layer composite extends to a depth (d 15), which is smaller than a thickness (d 10) of the first layer composite, characterized in that the first layer composite further comprises an auxiliary layer different from the structured layer, which adheres well to the structured layer, can be removed again, and adjoins a second surface of the structured layer, with the second surface of the structured layer lying opposite the first surface of the structured layer, and the filled trench extends to the second surface of the structured layer.
