    Abstract: The invention relates to a method for contacting a doping area (3) which is formed on the surface (2) of a substrate (1). According to the invention, an isolating layer (5) is applied to the surface of the substrate (2) and a contact hole (16) is formed in the isolating layer (5). Subsequently, a layer containing metal (6) is placed on the isolating layer (5) and the surface area (4) of the doping area (3) which is bared by means of a contact hole (16). A two-stepped temperature process then follows, whereby in the first step the layer containing metal (6) is reacted with the silicon of the doping area (3) in order to obtain a metal silicon layer (7), and subsequently in the second temperature step the remaining layer containing metal (6) is transformed into a layer (8) containing metal nitrides.

    Abstract: A method makes contact with a doping region formed at a substrate surface of a substrate. An insulating layer is applied on the substrate surface and a contact hole is formed in the insulating layer. A metal-containing layer is subsequently deposited on the insulating layer and the surface region of the doping region that is uncovered by the contact hole. In a subsequent thermal process having two steps, first the metal-containing layer is reacted with the silicon of the doping region to form a metal silicide layer and then the rest of the metal-containing layer is converted into a metal-nitride-containing layer in a second thermal step.
