VPG+ 800 / VPG+ 1400

Designed for photomask production on large substrates in display applications

These large area VPG+ tools are tailored for high-throughput patterning of large-area wafers (from 0.8 to 1.4 m). The VPG+ 1400 is our largest system specifically designed for the display industry. It is optimal for flat panel display (FPD) applications such as TFT-arrays, color filters and ITO. These tools are also used for industrial large area photomask applications for advanced packaging, semiconductors, LEDs, and touch panel applications.

The VPG+ series is designed for high-quality and fast exposures with extremely accurate alignment. It features a differential interferometer with a resolution down to 1.2 nm. Mura optimization ensures excellent CD uniformity and resolution. The closed-loop environmental chambers comply with the most stringent requirements for advanced photomasks fabrication. Stabilization of writing conditions ensures mask-to-mask reproducibility and compensates for any variations during long exposures. The VPG+ systems support all industrial data formats.
