摘要： Embodiments of the present invention generally relate to apparatus for reducing arcing and parasitic plasma in substrate processing chambers. The apparatus generally include a processing chamber having a substrate support, a backing plate, and a showerhead disposed therein. A showerhead suspension electrically couples the backing plate to the showerhead. An electrically conductive bracket is coupled to the backing plate and spaced apart from the showerhead. The electrically conductive bracket may include a plate, a lower portion, an upper portion, and a vertical extension. The electrically conductive bracket contacts an electrical isolator.

摘要： A chemical mechanical polishing system includes a substrate support configured to hold a substrate, a polishing pad assembly include a membrane and a polishing pad portion having a polishing surface, a polishing pad carrier, and a drive system configured to cause relative motion between the substrate support and the polishing pad carrier. The polishing pad portion is joined to the membrane on a side opposite the polishing surface. The polishing surface has a width parallel to the polishing surface at least four times smaller than a diameter of the substrate. An outer surface of the polishing pad portion includes at least one recess and at least one plateau having a top surface that provides the polishing surface. The polishing surface has a plurality of edges defined by intersections between side walls of the at least one recess and a top surface of the at least one plateau.

摘要： A flow of a remotely-generated plasma to a processing chamber by-passes a blocker plate and thereby avoids unwanted recombination of active species. By-passing the blocker plate according to embodiments of the present invention avoids the high pressures arising upstream of the blocker plate, inhibiting ion recombination and elevating the concentration of reactive ions available in the processing chamber for cleaning and other reactions. In accordance with one embodiment of the present invention, the flowed ions may be distributed beyond the edge of an underlying blocker plate through channels of a separate by-pass plate positioned between the gas box and the blocker plate. In accordance with an alternative embodiment in accordance with the present invention, the flow of remotely generated active ion species may be distributed beyond the edge of an underlying blocker plate through channels of the gas box itself.

摘要： A gas mixing system for a semiconductor wafer processing chamber is described. The mixing system may include a gas mixing chamber concentrically aligned with a gas transport tube that extends to a blocker plate. The gas mixing chamber and the transport tube are separated by a porous barrier that increases a duration of gas mixing in the gas mixing chamber before processes gases migrate into the transport tube. The system may also include a gas mixing insert having a top section with a first diameter and a second section with a second diameter smaller than the first diameter and concentrically aligned with the top section. The processes gases enter the top section of the insert and follow channels through the second section that cause the gases to mix and swirl in the gas mixing chamber. The second section extends into the gas mixing chamber while still leaving space for the mixing and swirling around the sidewalls and bottom of the mixing chamber.
