Chip reticle
For IC production in the 1960s and early 1970s, an opaque rubylith film laminated onto a transparent mylar sheet was used. The design of one layer was cut into the rubylith, initially by hand on an illuminated drafting table (later by machine (plotter)) and the unwanted rubylith was peeled off by hand, forming the master image of that layer of the chip. Increasingly complex and thus larger chips required larger and larger rubyliths, eventually even filling the wall of a room.

With high end chips starting to reach the reticle limit for current steppers, and with High NA EUV halving the reticle limit, it seems like reticle limit is becoming a bigger issue for VLSI chip manufacturing and design.
WebTypical reticle sizes are from 10 to 20 mm square (but not necessarily square), so you might get 40 or 50 reticles on a 100 mm diameter wafer. Note that because the pattern is repeated, you can't write unique chip numbers using projection lithography, you'd have to use a contact mask or write the numbers one by one using your e-beam.
