ABSTRACT:
A method of manufacturing a device, preferably a semiconductor device, having a pattern of conductors provided on a substrate. According to the invention a pattern of conductors with very fine details can be obtained by providing the pattern in at least two parts and at least two steps, in which in each step an auxiliary layer is provided over the assembly which is patterned so as to correspond with the negative of the part of the pattern of conductors to be provided, after which a conductive layer is provided over the assembly and at least a part of the auxiliary layer with the part of the conductive layer present thereon is then removed.
