摘要:
Apparatus for treating wafers using a wafer carrier rotated about an axis is provided with a ring which surrounds the wafer carrier during operation. Treatment gasses directed onto a top surface of the carrier flow outwardly away from the axis over the carrier and over the ring, and pass downstream outside of the ring. The outwardly flowing gasses form a boundary over the carrier and ring. The ring helps to maintain a boundary layer of substantially uniform thickness over the carrier, which promotes uniform treatment of the wafers.
