JENA/Germany, 12.08.2015.
In order to achieve specifications for high end photomasks reliably, the Advanced Mask Technology Center (AMTC), a joint venture of GLOBALFOUNDRIES and Toppan Photomasks, has integrated a ZEISS CDC/RegC system into their Dresden facility. The tool can improve Critical Dimension (CD) uniformity of photomasks with high accuracy. In addition it includes a registration repair functionality enabling mask registration and wafer overlay improvement.
Continuously shrinking designs by further extension of 193nm technology lead to increased requirements in terms of overlay, registration and Critical Dimension uniformity across the mask. With CDC/RegC tool we have proven technology to fine-tune these critical parameters to better support the needs of our wafer fab customers. states AMTC.
AMTC is already familiar with the concept of CD and REG repair based on a first generation tool of the same tooltype which was evaluated and used at AMTC. Now, with the more mature tool this concept will be brought into the mask production to help increase performance at the wafer fab of AMTC's parent-companies and in the mask house. The ZEISS CDC/RegC Combo improves CD uniformity (CDU) and registration uniformity across photomasks with high repeatability and precision by employing a femtosecond laser technology. By the use of a dedicated algorithm combined with a tunable laser system, the laser pulse implants arrays of dots in the glass bulk with adjustable optical and mechanical properties. This enables the mask manufacturer to help the chip makers to meet tightest CDU and registration/overlay specifications.
