Bruker's New AcuityXR Technology Breaks Diffraction Limit

(Nanowerk News) Bruker Corporation announced today at the Materials Research Society (MRS) Fall 2010 Meeting the AcuityXR™, a novel optical surface profiler mode that combines unique, patent-pending Bruker hardware and software technology to enable select ContourGT™ non-contact, 3D optical surface profilers to break the optical diffraction limit and deliver lateral resolutions that were previously considered impossible to achieve.
Many nanoscale applications in the semiconductor, medical and precision machining fields today have surface features and defects with dimensions that limit detection or identification due to the optical diffraction limit. Such miniscule features and defects often directly affect function, performance, quality and/or manufacturing yields and are of great interest to researchers and production QA/QC personnel alike. Bruker optical surface profiler systems equipped with the new AcuityXR mode have shown resolution of features below 130 nanometers in width, which is unprecedented in optical microscopy and is nearly three times finer than for systems without this technology. Furthermore, AcuityXR enables this new level of precision while preserving the wide field-of-view and high performance benefits of Bruker non-contact, 3D optical surface profiling. With AcuityXR, dimensional repeatability on narrow structures has been shown to improve by more than a factor of 5x, showing a true metrology benefit to the technology in addition to its ability to reveal exceptionally fine features. AcuityXR is an optional capability that is now available on Bruker ContourGT-K1, X3 and X8 optical surface profilers.
"AcuityXR combines radically new measurement algorithms with the enhanced metrology hardware technology in the ContourGT-K1, X3 and X8 systems that together deliver lateral resolutions never before achieved in optical microscopy," said Mr. Ross Q. Smith, Vice President and General Manager of Bruker's Stylus & Optical Metrology Unit. "This remarkable new capability, which is exclusively available on ContourGT systems, is a great benefit to both our current and prospective customers in semiconductor, medical and precision machining applications where feature sizes are shrinking while the need for quality is continuously increasing."
Dr. Mark R. Munch, President of the Bruker Nano Surfaces Business, added: "AcuityXR builds upon the industry-leading performance, repeatability and ease-of-use capabilities of the ContourGT product family. Bringing this unprecedented achievement to market truly illustrates Bruker's on-going commitment to provide the highest value nanosurface metrology systems to our industrial and R&D customers."
AcuityXR and ContourGT at the MRS 2010 Fall Meeting
ContourGT systems equipped with AcuityXR will be demonstrated at the Bruker Nano Surfaces Booth (No. 300) at the MRS Fall Meeting held at the Hynes Convention Center in Boston, MA, November 30 through December 2. Bruker will be conducting a seminar on AcuityXR and other advanced optical surface measurement modes on Tuesday, November 30 at 6:30 PM in the Sheraton Boston Hotel, 3rd Floor, Beacon G.
About the ContourGT Family
Introduced earlier in 2010, the ContourGT family of non-contact, 3D optical surface profilers features Bruker-patented, high-brightness dual-LED illumination that, when combined with the system's superior vertical resolution, greatly improves sensitivity and stability and enables precision non-contact 3D surface metrology in difficult applications and environments that are challenging for other WLI-based systems. The ContourGT also features the new Bruker-developed and patent-pending Vision64™ operating and analysis software and the industry's most intuitive, modular user interface that provides user-level-customization capabilities for a wide range of surface profiling metrology applications.
