Abstract
A fixture for cutting thin substrates, such as films, wafers, semiconductor layers and the like, using a blade holder assembly joined to a substrate clamp assembly. Each assembly has a plurality of members with the substrate clamp having a base plate that introduces a vacuum environment and a substrate support plate that uses the vacuum to secure the substrate in place. The blade holder assembly has interlocking projections in interleaving sheet members sandwiched between two bracket members that define slots for supporting a knife. Multiple slots allow the blade to be positioned in different positions and different orientations for cutting thin substrates held with vacuum pressure in the substrate clamp assembly.
