Lithography k1
Web7 apr. 2024 · All these challenges are mainly driven by lithography. With the development of advanced photoresists (PRs), the resolution factor K1 in projection lithography reduces from 0.66 to 0.39, improving the resolution by 40% without the negative impacts on the depth-of-focus (DOF). WebUsing lithography with shorter wavelengths of light and more powerful optical systems enables smaller, denser and more powerful microchips. The last part of the Rayleigh …
