Claim:
A wafer holding device, comprising: a plate having a top side including a surface and a bottom side spaced from the top side by a thickness, the plate dimensioned to receive a wafer on the top side, the plate including a handling tab positioned at a first end of the plate and extending outward from the first end, a second end of the plate opposite the first end being curved; a retaining feature positioned at the second end and having a first extension from the plate and a second extension from the first extension extending over at least a portion of the surface, the first and second extensions defining a recess; and a plurality of features formed on the surface of the plate, distributed substantially uniformly across an area of at least approximately 100 mm in diameter on the surface, the top side dimensioned such that the wafer positioned on the top side is in contact with and supported by at least some of the features formed on the surface such that the wafer is offset from the surface by a height defined by the plurality of features and positioned over the surface, the recess dimensioned to retain the wafer and accommodate the height.
