ZEISS launches photomask repair tool MeRiT HR II

GERMANY: The new generation system MeRiT HR II from ZEISS offers a significantly higher degree of automation and increased flexibility in the repair of transparent and opaque defects.

Any defect geometry on all known as well as new mask types and materials can be processed: Binary, OMOG, HD MoSi and EUV. The technical specifications of the MeRiT® HR II match to the industry roadmap and sharp market requirements.

The redesigned tool includes a sound automation package which enables a new level of automation with optimized repair flow. After a short setup routine the processes are able to seamlessly repair numerous defects without the need for human interaction. A higher throughput due to lower idling time is also offered. In case of any doubt a security interlock consults the operator who can intervene when necessary.

“The significantly improved automation level of the new MeRiT HR II frees up precious operator time. Furthermore the combination of automation and manual repair provides an increased flexibility. Altogether the new system has its finger on the pulse as it includes the most relevant requirements mask shops have for repairing all kinds of photomask types in a very short time.” states Dr. Oliver Kienzle, head of the ZEISS strategic business unit Semiconductor Metrology Systems who develops and sells the MeRiT HR II.
