Web6 mrt. 2024 · Below is a simplified depiction of “litho-etch-litho-etch (LELE),” one of the most common multi-patterning schemes. We will bucket other schemes like SADP and LELB into the same bucket as LELE for simplicities sake here.

Web3 mrt. 2024 · Extreme ultraviolet (EUV) lithography with a wavelength of 13.5 nm extends optical projection lithography into the spectral range of soft x-rays. There are no materials that transmit light at these small wavelengths. As explained in Chapter 6, extreme ultraviolet (EUV) lithography has to employ reflective optics and mask, but also novel light ... http://classweb.ece.umd.edu/enee416/GroupActivities/Lithography.pdf
