Witryna2.3.3 Extreme ultraviolet lithography (EUVL) technology. EUVL technology is an advanced technology with a light source of 13.5 nm, which is extremely short wavelength and can be applied for beyond the 10 nm node. EUVL enables the use of only one mask exposure instead of multiexposure. However, there are still three issues to be solved … WitrynaImmersion lithography is a photolithography resolution enhancement technique for manufacturing integrated circuits (ICs) that replaces the usual air gap between the final lens and the wafer surface with a liquid medium that has a refractive index greater than one. The resolution is increased by a factor equal to the refractive index of the liquid. …
