Abstract
The invention concerns an integrated circuit the monocrystalline or polycrystalline silicon zones of which the source, gate and drain are covered with tantalum silicide TaSi.sub.2 while the remainder of the slice is covered with portions of a layer of tantalum oxide Ta.sub.2 O.sub.5, especially on the sides of the grids of polycrystalline silicon and on the thick oxide and an aluminum alloy layer comes into contact with the tantalum silicide to form connections with the portions of tantalum silicide.
