A fundamental aspect of EUVL tools, resulting from the use of reflective optics, is the off-axis illumination (at an angle of 6 degrees, in different direction at different positions within the illumination slit) on a multilayer mask. This leads to shadowing effects resulting in asymmetry in the diffraction pattern that degrade pattern fidelity in various ways as described below. For example, one side (be… WebASML Berlin GmbH (formerly Berliner Glas GmbH) is a major ASML R&D and manufacturing site, with expertise in optics and wafer chuck technology.
