The Varian VIISta 900 3D system is the industry’s flagship medium-current ion implanter for high-volume manufacturing beyond the 2xnm node. Its beam-line architecture has been specially designed with the angle accuracy and beam shape control necessary for exact dopant placement and minimal within-wafer and wafer-to-wafer variability for applications in logic finFETs and 3D memory structures. These capabilities also benefit CMOS image sensor technology as well as the most advanced planar structures.
