Paper Abstract

Tri-layer resist technique has been developed for volume production of VLIs to achieve 0.8 um line and space pattern using an NA 0.35 stepper. The 0.8 um feature process was done mostly by optimizing normality of developer for top-layer resist. Obtained resolution dep ends strongly on normality of the developer. The lower normality gives much wider latitude to CD control. Possibility of application of tri-layer resist process whose struc,ture con-sists of top-layer resist, middle-layer silicon resin, and underlayer resist was examined.
