A photomask is created by writing or exposing the designer’s pattern onto a blank chrome mask with a resist coating. The resist latent image is developed to create the necessary pattern. As the etching procedure is being done, this resist picture serves as a mask.
It offers a complete solution, speeding throughput with previously unheard-of repair efficacy, from auto defect review through defect correction to repair verification. Defects of any kind can be repaired without any danger of harm. capable of handling EUV masks when used with a twin pod.
In order to create devices for consumer goods, computers and peripherals, military goods, automotive goods, and medical and biological goods, photomasks are frequently used. Photomasks are used in several colleges all over the world for both research and the development of new technology.
Glass masks and film masks are the two different categories of photomasks. Glass masks come in two varieties: chromium masks and emulsion masks.The devices allow for ultra-small flaws to be repaired using advanced electron beam columns that are optimised for low energies.
The Global Photomask Repair System market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
ZEISS Launches New Photomask Repair Tool MeRiT HR II. The new high resolution photomask repair tool MeRiT HR II which offers a high level of automation and a large variety of additional repair processes.The ZEISS MeRiT HR II next generation technology provides a much better degree of automation and enhanced flexibility in the correction of clear and opaque faults.
Any defect shape may be treated on all existing as well as novel mask types and materials, including binary, OMOG, HD MoSi, and EUV. The MeRiT HR II’s technological characteristics are in line.
The updated tool has a strong automation package that enables improved repair flow at a new degree of automation. The procedures are able to smoothly fix many faults after a brief setup sequence without requiring human input. Also provided is a higher throughput as a result of less idle time. A security interlock consults the operator when in doubt so that can take action if necessary.
