  • Publication number: 20070184210
    Abstract: Provided are an apparatus for depositing a thin film, and a method of depositing the thin film. The apparatus may include a vertical tube providing a space in which a thin film deposition process is performed, a plasma generator generating plasma in the vertical tube, a heater adjacent to the vertical tube for heating the vertical tube, and a boat receiving a plurality of wafers and rotatably disposed in the vertical tube. The method of depositing a thin film may include providing a wafer into a thin film apparatus, rotating the wafer, flowing a plasma across the wafer from edge to edge, depositing a first thin film on the wafer, creating a temperature gradient within the thin film apparatus, wherein the temperature at the center of the wafer is higher than the temperature at the edges of the wafer, and depositing a second thin film on the wafer.
