Abstract
Focused ion beam repair of opaque defects on 5X reticles cause a post repair stain due mainly to gallium ion implantation in the surface of the quartz substrate. The effects of these stains have been investigated through printability tests using a g-line optical lithography process. In some cases the effect of the post repair stain is worse than that of the original defect, highlighting the need for effective antistain processes for use in conjunction with FIB repair.
