Abstract
A semiconductor arrangement includes a substrate having a plurality of transistors formed therein and a tungsten layer thereon in the form of elongate tracks serving to interconnect the transistors. Localized regions of highly doped semiconductor material underlie the tracks and form an ohmic contact therewith. The tungsten layer is overlaid with an electrically insulating oxide on which further electrical interconnections are present.
