Overview

The NOVELLUS SABRE xT is a tool used for electrofilling that is part of the second generation of SABRE tools. It is designed to provide void-free fill in 0.13-micron geometries with aspect ratios up to 10:1. The SABRE xT is a “bridge tool” that can process either 200 or 300 mm wafers. It incorporates process enhancements in the areas of electrical waveforms, advanced bath chemistries, and automated chemical monitoring and control using Novellus’ proprietary SmartDose algorithm. The SABRE xT can process up to 75 wafers per hour and has achieved within-wafer uniformity performance of less than 2% 1 sigma and wafer-to-wafer uniformity of less than 1% 1 sigma in a production environment.
