Definitions
- the present invention relates to a polishing composition that can efficiently prevent metal contamination on a silicon wafer.
- a semiconductor silicon wafer manufacturing method includes a slicing process for slicing a single crystal ingot to obtain a thin disk-shaped wafer, and a method for preventing cracking and chipping of the wafer obtained by the slicing process.
- a polishing process for cleaning the polished wafer and removing foreign substances such as abrasives adhering to the polished wafer.
- a polishing composition is generally used in which fine silica particles are uniformly dispersed in water and further added with a chemical polishing accelerator such as inorganic alkali, ammonium salt, and amine. Polishing is performed.
- a chemical polishing accelerator such as inorganic alkali, ammonium salt, and amine. Polishing is performed.
- this alkaline silica-containing abrasive contains trace amounts of metal impurities.
- metal impurities contained in the abrasive include nickel, chromium, iron and copper. These metal impurities easily adhere to the silicon wafer surface in an alkaline solution. Adhering metal impurities, especially copper, diffuse easily into the silicon wafer crystal, which has a large diffusion coefficient. It is clear that the metal impurities that have diffused into the crystal cannot be removed by subsequent cleaning, which deteriorates the quality of the silicon wafer and degrades the characteristics of the semiconductor device using the wafer.
