Abstract

An electrical resistor has an electrically conductive stack, which includes a plurality of metal first layers and second layers. The stack allows to produce a highly anisotropic resistor, in which the resistance in the direction perpendicular to the layers is much higher than in the plane of the layers. The anisotropy allows the current flowing through the stack to be made homogenous, e.g., to be distributed over the entire stack surface, even if the current is input into the stack in an inhomogenous manner.
