Abstract:
1. A transportable wafer carrier device comprising: a wafer chuck comprising a top component and a bottom component and wherein said top component comprises a top surface and bottom surface and wherein said bottom component comprises an enclosed vacuum reservoir and is in contact with the bottom surface of the top component, and wherein the top surface of the component is configured to support a wafer so that a wafer surface comprising three-dimensional structures is in contact with the top surface of the top component; wherein said top component comprises one or more through-openings extending from the top surface to the bottom surface of the top component and communicating with the vacuum reservoir and wherein the wafer is held onto the top surface of the top component via vacuum from said vacuum reservoir drawn through said through-openings; wherein the top surface of the top component comprises three-dimensional support structures extending outward from the top surface of the top component and being shaped and dimensioned to support the wafer, and are aligned to points on the wafer surface configured to not interfere with bumps or bonds formed on the wafer surface.
