A chamber liner for use in a semiconductor process chamber and a semiconductor process chamber containing the chamber liner are disclosed. The process chamber includes a housing having an inner surface defining a chamber in which a vacuum is drawn during processing of a semiconductor wafer. The chamber liner has a plasma confinement shield with a plurality of apertures. An outer sidewall extends upwardly from the plasma confinement shield. An outer flange extends outwardly from the outer sidewall such that the outer flange extends beyond the chamber and into a space at atmospheric pressure. The chamber liner preferably further includes an inner sidewall that extends upwardly from the plasma confinement shield. The plasma confinement shield, the inner and outer sidewalls, and the outer flange are preferably integral with one another.

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.

A plasma confinement arrangement for controlling the volume of a plasma while processing a substrate inside a process chamber using a plasma enhanced process is disclosed. The arrangement includes a first magnetic bucket having a plurality of first magnetic elements. The first magnetic elements being configured for producing a first magnetic field inside the process chamber. The arrangement further includes a second magnetic bucket having a plurality of second magnetic elements. The second magnetic elements being configured for producing a second magnetic field inside the process chamber. The second magnetic field being configured to combine with the first magnetic field to produce a resultant magnetic field between the first magnetic bucket and the second magnetic bucket. The resultant magnetic field being configured to permit by-product gas from the processing to pass through while substantially confining the plasma within a volume defined at least by the process chamber and the resultant magnetic field.

Methods for orienting an upper electrode relative to a lower electrode are provided. The lower electrode is configured to have a desired existing orientation in a process chamber to define active and inactive process zones in the process chamber for processing a wafer. The method includes configuring each electrode with a reference surface, where a lower electrode reference surface is in the desired existing orientation and an upper electrode reference surface to be oriented parallel to the lower electrode reference surface. Then, temporarily holding the upper electrode reference surface oriented parallel to the lower electrode reference surface, and securing the upper electrode to a drive to mount the upper electrode reference surface parallel to the lower electrode reference surface. Other method configurations are also disclosed and illustrated.
