Abstract

A semiconductor device is fabricated and contains a first body made of an organic semiconductor material and a second body made of an electrically conductive contact material, that form a common contact area. First, a body is produced on a substrate, which body may be composed of the contact material or the organic semiconductor material, and an intermediate layer is applied thereon, the intermediate layer containing a reactive dopant. Afterward, a body made of the organic semiconductor material or the contact material is fabricated on the intermediate layer. The dopant contained in the intermediate layer effects a region-selective doping of the organic semiconductor material and, as a consequence, a significant reduction of the contact resistance for the transition of charge carriers between the contact material and the organic semiconductor material.
