Accelerating Data Collection and Analysis
Utilizing a unique direct-drive scan stage, the DektakXT accelerates measurement scan times by 40% while maintaining industry-leading performance. Vision64, Bruker’s 64-bit parallel processing operation and analysis software, enables faster loading of 3D files and faster applications of filters and multiscan database analyses.
Delivering the Most Repeatable Measurements
Implementing a single-arch structure makes the DektakXT sturdier, which minimizes the effects of environmental noise. DektakXT’s upgraded “smart electronics” reduce temperature variations and employ modern processors that minimize error-inducing noise, allowing it to be an even more robust system capable of measuring <10nm step heights.
Perfecting Operation and Analysis
Bruker’s Vision64 software complements DektakXT’s innovative design by providing the most intuitive and streamlined visual user interface. The combination of intelligent architecture and customizable automation capabilities allow for fast and comprehensive data collection and analysis. Whether you’re using a recipe to perform routine analysis on single scans, or applying custom filters settings and calculations, DektakXT’s Data Analyzer displays current data while also revealing other possible analyses.
Making Things Easy
The DektakXT’s self-aligning stylus assembly allows the user to quickly and easily change stylus size while eliminating any potential mishaps during the process. Bruker offers the widest range of stylus sizes to accommodate nearly any application need.
Ensuring High Yield
DektakXT provides the ability to quickly and easily set up and run automated multi-site measurement routines to verify the precise thickness of thin films across the wafer surface with unmatched repeatability. This efficient monitoring can save valuable time and money by improving yields.
