Abstract:
1. An apparatus for supporting a semiconductor substrate during processing of the semiconductor substrate, the apparatus comprising: a support structure having an upper side and a lower side, the support structure being at least partially transparent, the upper side defining a working surface including a working area for supporting a semiconductor substrate during processing of the semiconductor substrate, the working surface defining vacuum openings configured to be connected to a vacuum source to retain the semiconductor substrate against the upper side during processing, the support structure including a plurality of non-planar light reflecting structures adjacent the lower side; and at least one light source emitting light into the support structure from a lateral side of the support structure, the lateral side being disposed between the upper side and the lower side, the emitted light interacting with the non-planar light reflecting structures to homogeneously illuminate the working area.
