One historic application of a coordinatograph was a machine that precisely placed and cut rubylith to create photomasks for early integrated circuits including some of the earliest generations of the modern PC microprocessor. The coordinatograph produced layout would then be photographically reduced 100:1 to create the production photomask.

The first chips at Intel used a machine called a “Coordinatograph” to guide cutting of the [rubylith].

(Semiconductor die patterns were usually produced at 100:1 using a scribe-coat coordinatograph where the coating was peeled away to leave the represented IC Pattern).
