    摘要: An apparatus for generating uniform plasma across and beyond the peripheral edge of a substrate has a dielectric body with an upper electrode and an annular electrode embedded therein. The outer perimeter of the upper electrode overlaps the inner perimeter of the annular electrode. In one embodiment, the upper electrode and the annular electrode are electrically coupled by molybdenum vias. In one embodiment, the upper electrode is coupled to a DC power source to provide electrostatic force for chucking the substrate. In one embodiment, the upper electrode is coupled to an RF source for exciting one or more processing gasses into plasma for substrate processing.

    摘要: An electrostatic chuck has an electrode embedded in a dielectric which is mounted on a pedestal. The dielectric has a contact surface with an average surface roughness of less than about 0.5 μm, a surface peak waviness of less than about 0.12 μm, and a surface peak waviness material ratio of greater than about 20%. The surface texture can be formed by lapping the dielectric surface with a slurry of abrasive particles.

    摘要: Methods and apparatus for processing substrates are provided herein. In some embodiments, an apparatus for processing a substrate includes a flow equalizer configured to control the flow of gases between a process volume and an exhaust port of a process chamber. The flow equalizer includes at least one restrictor plate configured to be disposed in a plane proximate a surface of a substrate to be processed and defines an azimuthally non-uniform gap between an edge of the at least one restrictor plate and one of either a chamber wall or a substrate support when installed in the process chamber.
