摘要： The invention is embodied in a method of cleaning a plasma reactor by creating a vacuum in the chamber while introducing an etchant gas into the chamber through the gas injection ports, and applying RF energy to a ceiling electrode in the chamber while not necessarily applying RF energy to the coil antenna, so as to strike a predominantly capacitively coupled plasma in the vacuum chamber. In another embodiment the method includes, whenever the reactor is to be operated in an inductive coupling mode, applying RF power to the reactors coil antenna while grounding the ceiling electrode, and whenever the reactor is to be operated in a capacitive coupling mode, applying RF power to the ceiling electrode, and whenever the reactor is to be cleaned, cleaning the reactor by applying RF power to the ceiling electrode and to the coil antenna while introducing an etchant gas into the vacuum chamber. In yet another embodiment the method includes performing chemical vapor deposition on a wafer by introducing a deposition precursor gas into the chamber while maintaining an inductively coupled plasma therein by applying RF power to the coil antenna while grounding the ceiling electrode, and cleaning the reactor by introducing a precursor cleaning gas into the chamber while maintaining a capacitively coupled plasma in the chamber by applying RF power to the ceiling electrode.

摘要： Methods and systems for handling a substrate through processes including an integrated electroless deposition process includes processing a surface of the substrate in an electroless deposition module to deposit a layer over conductive features of the substrate using a deposition fluid. The surface of the substrate is then rinsed in the electroless deposition module with a rinsing fluid. The rinsing is controlled to prevent de-wetting of the surface so that a transfer film defined from the rinsing fluid remains coated over the surface of the substrate. The substrate is removed from the electroless deposition module while maintaining the transfer film over the surface of the substrate. The transfer film over the surface of the substrate prevents drying of the surface of the substrate so that the removing is wet. The substrate, once removed from the electroless deposition module, is moved into a post-deposition module while maintaining the transfer film over the surface of the substrate.

摘要： Embodiments of the invention generally provide methods for end point detection at predetermined dopant concentrations during plasma doping processes. In one embodiment, a method includes positioning a substrate within a process chamber, generating a plasma above the substrate and transmitting a light generated by the plasma through the substrate, wherein the light enters the topside and exits the backside of the substrate, and receiving the light by a sensor positioned below the substrate. The method further provides generating a signal proportional to the light received by the sensor, implanting the substrate with a dopant during a doping process, generating multiple light signals proportional to a decreasing amount of the light received by the sensor during the doping process, generating an end point signal proportional to the light received by the sensor once the substrate has a final dopant concentration, and ceasing the doping process.

摘要： A method is provided for performing plasma immersion ion implantation with a highly uniform seasoning film on the interior of a reactor chamber having a ceiling and a cylindrical side wall and a wafer support pedestal facing the ceiling. The method includes providing a gas distribution ring with plural gas injection orifices on a periphery of a wafer support pedestal, the orifices facing radially outwardly from the wafer support pedestal. Silicon-containing gas is introduced through the gas distribution orifices of the ring to establish a radially outward flow pattern of the silicon-containing gas. The reactor includes pairs of conduit ports in the ceiling adjacent the side wall at opposing sides thereof and respective external conduits generally spanning the diameter of the chamber and coupled to respective pairs of the ports. The method further includes injecting oxygen gas through the conduit ports into the chamber to establish an axially downward flow pattern of oxygen gas in the chamber. RF power is coupled into the interior of each of the conduits to generate a toroidal plasma current of SixOy species passing through the chamber to deposit a seasoning layer of a SixOy material on surfaces within the chamber, while leaving the pedestal without a wafer so as to expose a wafer support surface of the pedestal.
