METHODS FOR PROCESSING A SUBSTRATE USING MULTIPLE SUBSTRATE SUPPORT POSITIONS

摘要

In some embodiments, a method for processing a substrate in a process chamber having a substrate support configured to move in a direction perpendicular to a top surface of a cover ring of a process kit may include positioning the substrate support in a first position such that a top surface of the substrate is positioned about 3 mm above to about 10 mm below a top surface of a cover ring of a process kit disposed about the periphery of the substrate support; performing a plasma deposition process while the substrate support is in the first position; moving the substrate support to a second position such that the top surface of the substrate is disposed about 3 mm below to about 15 mm above the top surface of the cover ring; and performing a plasma etch process while the substrate support is in the second position.

1. A method for processing a substrate in a process chamber having a substrate support configured to move in a direction perpendicular to a top surface of a cover ring of a process kit, the method comprising:
positioning the substrate support in a first position such that a top surface of the substrate is positioned about 3 mm above to about 10 mm below a top surface of a cover ring of a process kit disposed about the periphery of the substrate support; performing a plasma deposition process within the process chamber while the substrate support is in the first position; moving the substrate support to a second position such that the top surface of the substrate is disposed about 3 mm below to about 15 mm above the top surface of the cover ring, wherein the second position is different from the first position; and performing a plasma etch process within the process chamber while the substrate support is in the second position.
