| 词条 | Coordinatograph |
| 释义 |
A coordinatograph is an instrument which mechanically plots X and Y coordinates onto a surface, such as in compiling maps[1] or in plotting control points such as in electronic circuit design. 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.[2] The coordinatograph produced layout would then be photographically reduced 100:1 to create the production photomask.[3] See also
