WebThe meaning of HALF-PITCH is having a gradient of one to two. How to use half-pitch in a sentence. 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…
