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… WebIn lithography, using shorter light wavelengths enables chipmakers to shrink the size and increase the density of the features (or transistors) on a chip, making the chip faster and … how can men regrow hair
