…utilization of the excimer beam more optical elements must be added which homogenize the raw beam and illuminate the exact mask pattern. The principle of a high efficient homogenizer built by MicroLas is shown in Figure 4. Figure 4: Principle of Beam Homogenizer using crossed arrays of cylindrical…
