Rotate-and-pull mechanisms for fiber optic modules. In this situation, nickel elements remain in a crystallized silicon film. In some embodiments the system includes a wire exit aperture. Therefore, the method according to the invention and the device according to the invention can very well be used in particular in mobile devices, as for example in hearing devices. The common body may be positioned vertically between a buried oxide layer and a gate dielectric layer and laterally between first and second sourcedrain regions formed in a semiconductor layer.
