METHOD AND APPARATUS FOR PLASMA DICING A SEMI-CONDUCTOR WAFER

摘要

The present invention provides a method for plasma processing a substrate. The method comprising providing a process chamber having a wall; providing a plasma source adjacent to the wall of the process chamber; providing a work piece support within the process chamber; loading a work piece onto the work piece support, the work piece having a support film, a frame and the substrate; providing a cover ring above the work piece, the cover ring having at least one perforated region, and at least one non-perforated region; generating a plasma using the plasma source; and processing the work piece using the generated plasma.
