摘要： An electrostatic clamp which more effectively removes built up charge from a substrate prior to removal is disclosed. Currently, the lift pins and the ground pins are the only mechanism used to remove charge from the substrate after implantation. The present discloses describes an electrostatic chuck in which the top dielectric surface has an embedded conductive region, such as a ring shaped conductive region in the sealing ring. Thus, regardless of the orientation of the substrate during release, at least a portion of the substrate will contain the conductive region on the dielectric layer of the workpiece support. This conductive region may be connected to ground through the use of conductive vias in the dielectric layer. In some embodiments, these conductive vias are the fluid conduits used to supply gas to the back side of the substrate.

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.
摘要翻译：静电卡盘包括具有多个突起以支撑工件的层，其中该层的至少一部分具有第一多个多个突起。第一多个突起间隔几何形成六边形图案。第一多个突起可以与相邻的突起间隔开相等的距离，并且等距离可以是距离一个突起的中心到另一个突起的中心的约4.0毫米。本公开减少了沿着每个突起的边缘常规存在的峰值机械应力水平。降低这种机械应力水平有助于减少支撑的工件的背面损坏，这又可以减少由这种损坏引起的不想要的颗粒的产生。

摘要： A method for cleaning a workpiece support that includes using a workpiece that has been coated on its bottom surface with a suitable material is disclosed. This specially coated workpiece is placed on the support, and some time later, it is removed, taking with it particles from the support. In certain embodiments, the workpiece undergoes an ion implantation process to increase its temperature, and to increase the tackiness of the coating on the bottom surface. The material used to coat the bottom can be of variable types, including photoresists, oxides and deposited glasses.
