    摘要: A plasma processing system for processing a substrate which includes a single chamber, substantially azimuthally symmetric plasma processing chamber within which a plasma is both ignited and sustained for the processing. The plasma processing chamber has no separate plasma generation chamber. The plasma processing chamber has an upper end and a lower end. The plasma processing system includes a coupling window disposed at an upper end of the plasma processing chamber and an RF antenna arrangement disposed above a plane defined by the substrate when the substrate is disposed within the plasma processing chamber for the processing. The plasma processing system also includes an electromagnet arrangement disposed above the plane defined by the substrate. The electromagnet arrangement is configured so as to result in a radial variation in the controllable magnetic field within the plasma processing chamber in the region proximate the coupling window and antenna when at least one direct current is supplied to the electromagnet arrangement. The radial variation is effective to affect processing uniformity across the substrate. The plasma processing system additionally includes a dc power supply coupled to the electromagnet arrangement. The dc power supply has a controller to vary a magnitude of at least one direct current, thereby changing the radial variation in the controllable magnetic field within the plasma processing chamber in the region proximate the antenna to improve the processing uniformity across the substrate.

    摘要: Positional relationships are established in a process chamber. A base is configured with a lower electrode surface to support a wafer, and an upper electrode has a lower surface. A drive mounted on the base has a linkage connected to the upper electrode. A fixture placed on the lower surface moves into a desired orientation of the lower electrode. With the upper electrode loosely connected by the linkage to the drive, the fixture transfers the desired orientation to the upper electrode. The linkage is tightened to maintain the desired orientation, the fixture is removed and a process exclusion insert is mounted to the upper electrode. The drive moves the upper electrode and the insert to define an inactive process zone between the upper electrode and the wafer on the lower electrode to protect a central area of the wafer during etching of a wafer edge environ around the central area.
