A silicon wafer having no epitaxially deposited layer or layer produced by joining to the silicon wafer, with a nitrogen concentration of 1·1013-8·1014 atoms/cm3, an oxygen concentration of 5.2·1017-7.5·1017 atoms/cm3, a central thickness BMD density of 3·108-2·1010 cm−3, a cumulative length of linear slippages ≦3 cm and a cumulative area of areal slippage regions ≦7 cm2, the front surface having 0.13 μm LSE in the DNN channel, a layer at least 5 μm thick, in which ≦1·104 COPs/cm3 with a size of ≧0.09 μm occur, and a BMD-free layer ≧5 μm thick. Such wafers may be produced by heat treating the silicon wafer, resting on a substrate holder, a specific substrate holder used depending on the wafer doping. For each holder, maximum heating rates are selected to avoid formation of slippages.
