Abstract

Official abstract text for this publication.

A workpiece chuck includes a supporting platform, a vacuum system, and a gas permeable buffer layer. The supporting platform has a supporting surface for holding a workpiece thereon. The vacuum system is disposed under and in gas communication with the supporting platform. The gas permeable buffer layer is disposed over the supporting platform and covers the supporting surface, wherein a hardness scale of the gas permeable buffer layer is smaller than a hardness scale of the supporting platform.

First claim
