METHODS FOR REDUCING DAMAGE TO SUBSTRATE LAYERS DURING DEPOSITION PROCESSES

摘要

Methods of processing a substrate are provided herein. In some embodiments, a method of processing a substrate may include providing a substrate to a process chamber comprising a dielectric layer having a feature formed therein. A barrier layer may be formed within the feature. A coating of a first conductive material may be formed atop the barrier layer. A seed layer of the first conductive material may be formed atop the coating. The feature may be filled with a second conductive material. In some embodiments, the seed layer may be formed while maintaining the substrate at a temperature of greater than about 40 degrees Celsius.
