Abstract (en)
[origin: WO2014137905A2] The present invention provides a method for plasma dicing 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; placing the substrate onto a support film on a frame to form a work piece work piece; loading the work piece onto the work piece support; providing a clamping electrode for electrostatically clamping the work piece to the work piece support; providing a mechanical partition between the plasma source and the work piece; generating a plasma through the plasma source; and etching the work piece through the generated plasma.
