29 December 1993 Acousto-optic scanning system for a large-size mask plotter
Author Affiliations +
A two-beam laser scanning system using an acousto-optic deflector (AOD) has been developed. The lensing effect and the AOD nonlinearity were investigated, and were completely compensated for. In order to write a variety of masks, a servomotor-based auto- focus and an auto-revolver with up to three objective lenses were adopted.
