SOL300

Black border laser annealing SOL300 is a black border laser annealing system, which reduces the reflectivity of EUV
masks by forming a “black” border around the die pattern area.

In contrast to traditional etching technique, black border laser annealing reduces particles,
improves mask quality as well as reduces the total cost of ownership.
