Résumé

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 R&D tool. Binary and multilevel plotting are demonstrated with plot rates of several Mpixels/s and 1 micron feature sizes into standard industrial photoresists. The limitations on plot rate and resolution are presented and techniques for overcoming them discussed.
