Abstract
A semiconductor configuration with an ohmic contact-connection includes a p-conducting semiconductor region made of silicon carbide. A p-type contact region serves for the contact-connection. The p-type contact region is composed of a material containing at least nickel and aluminum. A substantially uniform material composition is present in the entire p-type contact region. A method for contact-connecting p-conducting silicon carbide with a material containing at least nickel and aluminum is also provided. The two components nickel and aluminum are applied simultaneously on the p-conducting semiconductor region.
