摘要： A semiconductor element includes a semiconductor layer having a first doping density, a metallization, and a contact area located between the semiconductor layer and the metallization. The contact area includes at least one first semiconductor area that has a second doping density higher than the first doping density, and at least one second semiconductor area in the semiconductor layer. The second semiconductor area is in contact with the metallization and provides lower ohmic resistance to the metallization than a direct contact between the semiconductor layer and the metallization provides or would provide.
