Abstract
A method for stabilizing a tunnel junction component, in which a mask is formed on the surface of a substrate, and conductors are constructed by evaporation onto the substrate in an evaporation chamber, and at least one thin oxide layer element is oxidized on top of a selected conductor. This remains partly under the following conductor, thus forming a tunnel junction element with those conductors and titanium (Ti) or another gettering substance is evaporated on top of the said following conductor, before the tunnel junction component is removed from the evaporation chamber, when the titanium layer thus created protects the tunnel junction element from the detrimental effects of air molecules.
