A versatile photolithographic photoplotter based on a standard photoreduction stepper, where the reticle is replaced by a commercial liquid crystal microdisplay, is reported. The microdisplay module is designed as a drop-in replacement, allowing the photoplotter to be simply and quickly converted into a standard stepper, making it an extremely versatile, low-cost research and development tool. Binary and multilevel plotting are demonstrated with plot rates of several Mpixels/s and 1-m featuredoi:10.1117/1.2767331 fatcat:7b7xgapx7fb6ve7is2uxrwbh2q
