Abstract: In various embodiments, a method is provided. The method may include forming a buried electrically charged region at a predefined position in a first layer in such a way that the buried electrically charged region generates an electric field having a lateral inhomogeneous field distribution above the first layer, and forming a second layer above the first layer using the field distribution in such a way that a structure of the second layer correlates with the position of the buried electrically charged region.

Abstract: A mark configuration for the alignment and/or determination of a relative position of at least two planes in relation to one another in a substrate and/or in layers on a substrate during lithographic exposure, in particular, in the case of a wafer during the production of DRAMs, includes a mark structure, and at least one layer of a definable thickness underneath the mark structure for adjusting the physical position of the mark structure relative to a reference plane in or on the substrate. Also provided is a wafer having such a configuration and a process for providing such a configuration. The invention allows a mark configuration to have mark structures exhibiting good contrast regardless of the design or the process conditions.
