摘要： An apparatus is provided to improve clamping of a work piece to a support surface. The apparatus includes a support base, an insulator layer disposed on the support base, an electrode layer disposed on the insulator layer, and a clamping layer comprising aluminum oxynitride disposed on the electrode layer wherein the workpiece is clamped to the surface of the clamping layer. The apparatus provides a higher clamping force for the workpiece while reducing gas leakage and particle levels in addition to maintaining a declamping time suitable for high throughput processing. The apparatus may further provide a raised surface geometry or embossments on the dielectric or a dielectric comprising an outer ring a center cavity for reducing particle contamination to the backside of the workpiece. Also, a thin wall sleeve may be provided between the base and the insulator and alternating current may be applied to opposite ones of interdigitated electrode pairs to reduce particle contamination and improve the implantation uniformity.

摘要： An electrostatic chuck includes dielectric layer having at least one region, an electrode associated with the at least one region, and an AC power source configured to provide an AC voltage signal to the electrode. The dielectric property of the dielectric layer is configured to permit a charge migration about the dielectric layer to produce an electrostatic force to attract a workpiece to the dielectric layer when the AC voltage signal is applied to the electrode.

摘要： A system and method are disclosed for removing horizontally oriented substrates from a cassette. A substrate lifter has an engagement end for engaging a substrate and an adjustment end for engaging an adjustment assembly. The engagement end includes a recess having first and second arcuate sidewalls configured to engage an OD of the substrate, and a circular protrusion positioned between the first and second arcuate sidewalls. The circular protrusion allows lateral movement of the substrate up to a predetermined amount and prevents lateral movement of the substrate in excess of the predetermined amount. Other embodiments are described and claimed.

摘要： The present invention provides a rotating shaft that can extend between two regions having different ambient pressures. The rotating shaft can include a rotatable hollow outer shell that is coupled to a proximal portion of an inner shaft with a limited number of contact points. A plurality of thermal breaks disposed between the inner shaft and the hollow outer shell impede heat transfer between these two components. A rotary seal coupled to the distal portion of the inner shaft preserves the pressure differential between the two regions. Further, a heat sink removes heat transferred to the seal to ensure that the temperature of the seal remains within a range suitable for its operation. The rotating shaft of the invention can be utilized, for example, in an ion implantation system by the coupling of the outer shell to a wafer holder to position and orient a wafer in a path of an ion beam.
