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.
