A method and a device for handling errors of software modules for redundantly designed systems in vehicles in order to optimize error handling for redundantly designed systems in vehicles, so that errors are detected and error handling measures are introduced. The method includes providing a mask structure on a top surface of the thin film, depositing a semiconductor material above the top surface of the thin film and the mask structure, removing the semiconductor material to a level below the top surface of the mask structure, siliciding the semiconductor material, and providing a gate structure in an aperture formed by removing the mask structure. Furthermore, the phase change material or thermal battery may be used with a thermoelectric cooler to aid in ice production. The dispersing element and the elongated member are configured to rotate and precess relatively freely within the retaining structure. When a photographic copy is made, the masking function serves to counteract light falloff that existed in the master frame to produce a copy with reduced effect from light falloff.
