    摘要: A semiconductor wafer is formed of a substrate wafer of single crystal silicon doped with dopant atoms of the n type or p type, with a front surface and a back surface, contains a layer deposited epitaxially on the front surface of the substrate wafer. The substrate wafer additionally includes an n++ or p++ doped layer, which extends from the front surface of the substrate wafer into the substrate wafer and has a defined thickness. The semiconductor wafer is produced by a process in which dopant atoms of the n type or p type are introduced into the substrate wafer through the front surface of the substrate wafer, the dopant concentration in a layer which extends from the front surface of the substrate wafer into the substrate wafer being increased from the level n+ or p+ to the level n++ or p++, and an epitaxial layer is then deposited on this layer.

    摘要: A process for producing doped semiconductor wafers from silicon, which contain an electrically active dopant, such as boron, phosphorus, arsenic or antimony, optionally are additionally doped with germanium and have a defined thermal conductivity, involves producing a single crystal from silicon and processing further to form semiconductor wafers, the thermal conductivity being established by selecting a concentration of the electrically active dopant and optionally a concentration of germanium. Semiconductor wafers produced from silicon by the process have specific properties with regard to thermal conductivity and resistivity.
