Inductive transfer methods and structures combine, in a single system, at least two of the three functions of transferring power, communicating data, and sensing position with a vehicle on a guideway. A set of conductors is installed on the guideway to inductively couple a multiplicity of diverse signals with a corresponding set of conductors on the vehicle. The vehicle may be moving or stationary, and signals may be coupled in one or both directions. Coupling is effected without direct electrical contact, through a common region or gap, and the structures provide suitable and precise air gap control for the conductors effecting coupling of each signal.

In the method, which is to be carried out on a computer system, firstly design data of a semiconductor substrate are read in and, on the basis thereof, a mask image is generated in the form of a data structure with contact holes and with auxiliary structures on the computer system. Afterwards, contact hole biases are determined by means of an optical proximity correction method and the relevant contact holes are corrected on the basis of these contact hole biases. By means of subsequent imaging simulation of the mask image on the semiconductor substrate, undesired imaging auxiliary structures and contact holes deviating from specified tolerances on the semiconductor substrate are detected and corrected. During the imaging simulation of the mask image, a mask bias is employed in order to compensate for three-dimensional mask effects. A real mask can be produced on the basis of the mask image thus determined.
