发明名称 Optimized silicon wafer strength for advanced semiconductor devices
摘要 A method of manufacturing a damage-resistant silicon wafer is provided. The method comprises adding polycrystalline silicon to a crucible, adding a nitrogen-containing dopant to the crucible, heating the polycrystalline silicon to form a melt of nitrogen-doped silicon, pulling a nitrogen-doped silicon crystal from the melt using a seed crystal according to the Czochralski technique, forming a silicon wafer from the silicon crystal, the silicon wafer having an edge, and rounding the edge of the silicon wafer. The method may optionally include applying an electrical potential across the crucible while pulling the nitrogen-doped silicon crystal from the melt.
