Abstract: The rate of oxygen precipitation in a semiconductor wafer during heat treatment is reduced by quickly inserting the wafer into a furnace which has been preheated to the heat treatment temperature. After performing the heat treatment, the wafer is slowly cooled to prevent warpage or cracking.
