Method for processing substrate

A method and apparatus for processing a substrate are provided. The apparatus includes a pedestal and rotation member, both of which are moveably disposed within a processing chamber. The rotation member is adapted to rotate a substrate disposed in the chamber. The substrate may be supported by an edge ring during processing. The edge ring may selectively engage either the pedestal or the rotationmember. In one embodiment, the edge ring engages the pedestal during a deposition process and the edge ring engages the rotation member during rotation of the substrate. The rotation of the substrateduring processing may be discrete or continuous. 提供一种用于处理基板的方法与设备。该设备包括基座与旋转构件，基座与旋转构件可移动地设置在处理腔室内。旋转构件适配成旋转设置在腔室中的基板。在处理期间，基板可由边缘环支撑。边缘环可选择性地啮合基座或旋转构件。在一个实施例中，在沉积工艺期间，边缘环啮合基座，并且在基板的旋转期间，边缘环啮合旋转构件。处理期间的基板的旋转可以是不连续的或连续的。
