PRODUCT SPOTLIGHT: SensArray

KLA-Tencor's SensArray wafers provide a unique way -- not available through other means -- to monitor the effect of the process environment on semiconductor production wafers. Measurements are used by chipmakers and process equipment manufacturers to optimize and control their processes and process tools.

Process and equipment engineers alike utilize SensArray wafers throughout the fab for thermal information as an indicator of manufacturing equipment performance. With more advanced semiconductor manufacturing technologies -- such as smaller design rules, new materials, and new structures -- temperature control is becoming more critical.

WAFER METROLOGY

Addressing Thin Film Thickness Metrology Challenges of 14nm BEOL Layers

This paper describes a method to effectively monitor the film stack at different metal CMP process steps using a spectroscopic ellipsometer metrology tool. By proper modeling of the Cu dispersion and simulating the underlayer film information underneath the Cu pad, a single measurement recipe was developed which can be used to monitor each process step in the metal CMP process with stable and reliable results.
