KLA-Tencor Extends the Aleris(TM) Film Metrology Family With Two New Systems
SAN JOSE, Calif.--(BUSINESS WIRE)--
KLA-Tencor (NASDAQ:KLAC) today introduced two additions to its Aleris(TM) family of films metrology systems - the Aleris 8310 and Aleris 8350. These systems utilize KLA-Tencor's new generation of Broadband Spectroscopic Ellipsometry (BBSE(TM)) optics which allow chipmakers to measure multi-layer film thickness, refractive index, and stress, meeting advanced films metrology requirements.
The Aleris 8310 and 8350 join the Aleris 8500 system, announced in December 2007, which was the industry's first production-worthy system to enable compositional and multi-layer film thickness metrology in a single tool. The Aleris family of systems offers customers the ability to choose from a range of application-specific system configurations tailored to their exact technical requirements and economic conditions.
"The new Aleris product line now offers chipmakers a highly configurable set of advanced film metrology tools that cover both high-volume production fabs and future node development with a single platform architecture," noted Ahmad Khan, vice president and general manager of KLA-Tencor's Films and Scatterometry Technologies division. "By standardizing on this unique technology portfolio, our customers can move beyond their mix of unmatched and layer-dedicated metrology tools to a comprehensive metrology solution with the flexibility to meet fab-wide performance and cost of ownership (CoO) requirements for 45nm and beyond."
The Aleris Portfolio The Aleris portfolio builds on the company's industry-leading SpectraFx 200 technology, with different models aimed at different fab applications. The highly configurable and modular Aleris design enables flexibility in metrology capacity, sampling and extension to future nodes via upgradeability. The Aleris systems' new BBSE technology provides lower spectral distortion, higher signal-to-noise ratio and higher photon flux leading to significantly improved matching, precision and throughput than previous generations. The Aleris platform also offers higher reliability over the previous generation due to improved hardware components as well as leading edge software architecture and database. The Aleris 8500, launched in December 2007, features the unique 150nm BBSE technology, which enables the industry's first production product wafer monitoring of gate composition and thickness on a single tool. The Aleris 8350 is the best of breed advanced film thickness and refractive index metrology tool, enabling customers to meet tighter process tolerances. The 8350 covers the broadest range of 45nm applications, including diffusion, CVD, etch and other areas. The latest BBSE technology delivers up to 2x better thickness precision and 4x better refractive index matching than its predecessor due to improved spectral fidelity, optical sensitivity and stability. The system's 20% reduction in measurement box size also allows for measurements in smaller scribelines. The new StressMapper technology enables full wafer stress uniformity monitoring on critical films in the BEOL such as ultra-low k dielectrics, and high-stress liners in the FEOL, at higher sensitivity and throughput than previous generation tools. The Aleris 8310 is a cost-effective and reliable production solution for simple, thick film applications, with industry leading throughput. The Aleris family's modular design allows extendibility to meet the growing needs of customers through multiple device nodes. Increased throughput of 30% (SE) to 60% (Reflectometer), compared to the previous generation, provides for lower operating cost. High throughput allows for high sampling rates, which are especially critical for SOI substrate manufacturers who are required to do 100% sampling to meet their customer's tight requirements.
A matched Aleris metrology tool set can be shared across many fab applications, improving capacity flexibility and utilization, while significantly reducing metrology cost of ownership. The Aleris family also utilizes common recipes, training, software, and spare parts to boost fab ramp and efficiency.
Aleris systems have been shipped to key customers in all fab segments (memory, logic, and foundry) worldwide where they are being used for production and advanced development.
