The present invention describes a method including: providing a substrate; stacking interlevel dielectric layers over said substrate, and separating said interlevel dielectric layers with a dielectric separator layer. In one example, a system includes a plurality of storage partitions, each partition including a portion of a large scale data store, and metadata corresponding to the portion of the large scale data store. The turn guide plate is formed such that a front edge of the paper sheet transported to the turn portion is guided to a contact portion between a pinch roller arranged on a downstream side and the drive roller. The flatbed punching module can advantageously be used in a flatbed punch for processing a printing material web. Status information and supporting documents associated with the selected certificate can be retrieved from a remote server and portions of the retrieved information can be displayed. Said drive comprises a motor and a toothed gearing coupled with said motor, said toothed gearing being mounted in an at least two-piece housing and being driven by an internal gear.
