Lithography equation

WebLithography systems have progressed from blue wavelengths (436nm) to UV (365nm) to deep-UV (248nm) to today’s mainstream high resolution wavelength of 193nm. In the meantime, projection tool numerical apertures have risen from 0.16 for the first scanners to amazingly high 0.93 NA systems today producing features well under 100nm in size.

Web29 okt. 2024 · High-NA EUV lithography brings a second reason for using thinner resist films. Following a second Rayleigh equation, the depth-of-focus (DOF) – i.e., the resist height across which the (aerial) image is in focus – decreases by the square of the numerical aperture. Webthe reinitialization equation φt +sign(φ)( ∇φ −1) = 0 (13) for a short period of time.
