Flare lithography
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… WebFeb 17, 2024 · Lithography is employed to fabricate complicated circuit patterns on a semiconductor substrate. In the pursuit of faster processing speeds and large-scale integration, the critical dimension (CD) of circuit patterns has become increasingly small.
