A method of manufacturing a silicon wafer with robust gettering sites and a low concentration of surface defects is provided. The method comprises adding polycrystalline silicon to a crucible; adding a nitrogen-containing dopant to the crucible; heating the crucible to form a nitrogen-doped silicon melt; pulling a silicon crystal from the melt according to the Czochralski technique; forming a silicon wafer from the silicon crystal, wherein the silicon wafer includes a front surface and a back surface; placing the silicon wafer into a deposition chamber; heating the wafer; and simultaneously depositing an epitaxial first film of a desired compound onto the front surface of the wafer and a second film of the desired compound onto the back surface of the wafer.
