New Mask System for EUV Use

ZEISS Launches ForTune EUV: a Novel, High Performance Mask Tuning System for EUV Technology

ZEISS introduces the new ZEISS ForTune EUV system for EUV photomask tuning in both mask shops and wafer fabs.

JENA/Germany, 2017-09-11.

The new ZEISS ForTune EUV is a novel, state-of-the-art Mask Tuning system for EUV technology using ultrashort pulse laser technology. EUV technology presents new challenges with respect to mask registration and especially intra-field Mixed & Matched Overlay between DUV and EUV layers. The system has been specifically designed to support EUV lithography by improving the mask registration performance of EUV masks and wafer intra-field overlay.

With its advanced technology, ZEISS ForTune EUV enables accurate and reliable tuning process control with significantly enhanced performance:

  • by achieving registration improvement (mask level) > 70%
  • by reducing intra-field EUV – DUV Mixed & Matched Overlay (MMO) to the sub nanometer range (wafer level)

The ZEISS ForTune EUV system processed the first customer EUV masks, exceeding the expected results of registration error below 1 nm.

The mask tuning system will be presented for the first time to all mask shops and wafer fab customers at the SPIE Photomask Technology & Extreme Ultraviolet Lithography Conference in Monterey, California/USA in September 2017.

“ZEISS ForTune EUV uses advanced optical technology designed for EUV challenges, in combination with accurate process algorithm and high computational power. It is a powerful new technology that enables EUV mask makers and wafer fabs to tackle the registration and overlay challenges in a fast and cost-effective way,” states Alla Bitensky, Product Manager for Photomask Tuning products.
