Abstract:
1. A semiconductor substrate processing system, comprising: a processing chamber; a substrate support defined to support a substrate in the processing chamber; a plasma chamber defined separate from the processing chamber, the plasma chamber defined to generate a plasma; a plurality of fluid transmission pathways fluidly connecting the plasma chamber to the processing chamber, the plurality of fluid transmission pathways defined to supply reactive constituents of the plasma from the plasma chamber to the processing chamber; an electron beam source defined to generate an electron beam and transmit the electron beam through the processing chamber above and across the substrate support, wherein the electron beam source includes a hollow cathode positioned outside a perimeter of the substrate support and above the substrate support, the hollow cathode having an outlet oriented toward a region of the processing chamber over the substrate support; a plurality of conductive grids positioned outside a perimeter of the substrate support and above the substrate support, wherein a given one of the plurality of conductive grids is disposed between the outlet of the hollow cathode and the region of the processing chamber over the substrate support to facilitate extraction of electrons from the hollow cathode; and a heater connected to the plurality of conductive grids to control a temperature of the plurality of conductive grids.
