Abstract: The invention provides a method for depositing a film on a surface of a semiconductor wafer while preventing formation of defects on the surface of the wafer. The method includes selecting a quartz wafer carrier for holding the semiconductor wafer during the depositing of the film, where the wafer carrier has quartz rods with fire-polished slots for receiving an edge of the semiconductor wafer. The semiconductor wafer is placed into the quartz wafer carrier with the edge of the wafer disposed within the fire-polished slots, and the wafer carrier and wafer are loaded into a deposition chamber. Air is evacuated from the deposition chamber, the temperature in the chamber is raised to a deposition temperature, the pressure within the deposition chamber is adjusted to a deposition pressure, and process gases are introduced to the deposition chamber. By reaction of the process gases, the film is deposited on the surface of the wafer and on the wafer carrier.
