摘要: An electrostatic chuck includes a layer having a plurality of protrusions to support a workpiece, wherein at least a portion of the layer has a first plurality of the plurality of protrusions. The first plurality of protrusions is spaced to geometrically form a pattern of hexagons. The first plurality of protrusions may be spaced an equal distance from adjacent protrusions and the equal distance may be about 4.0 millimeters from a center of one protrusion to a center of another protrusion. The present disclosure reduces peak mechanical stress levels conventionally present along an edge of each protrusion. Reducing such mechanical stress levels helps reduce backside damage to a supported workpiece, which in turn can reduce the generation of unwanted particles caused by such damage.

摘要: Liner elements designed to protect the components located in the beam line are disclosed. These liner elements, preferably constructed from graphite, are coated with a non-metal material, such as silicon, silicon carbide or diamond like carbon. These coatings significantly reduce the loose particles created by the liner. Therefore, following preventative maintenance, the ion implantation system can return to normal operation sooner. A method of providing preventative maintenance for an ion implanter is also disclosed, whereby used liners are cleaned and recoated before being used again.

摘要: An electrostatic clamp, which more effectively removes built up charge from a substrate prior to and during removal, is disclosed. Currently, the lift pins and ground pins are the only mechanisms used to remove charge from the substrate after implantation. The present discloses describes a clamp having one of more additional low resistance paths to ground. These additional conduits allow built up charge to be dissipated prior to and during the removal of the substrate from the clamp. By providing sufficient charge drainage from the backside surface of the substrate 114, the problem whereby the substrate sticks to the clamp can be reduced. This results in a corresponding reduction in substrate breakage.

摘要: This device has a liner disposed on a face in a vacuum chamber. A component in the vacuum chamber defines the face. The liner is configured to protect the workpiece from contamination or to prevent blistering of the face caused by implantation of atoms or ions into the face. The liner may be disposable and removed from the face in the vacuum chamber and replaced with a new liner in some embodiments. This liner may be a polymer with a roughened surface, be carbon-based, or be composed of carbon nanotubes in some embodiments.
