Popis: A new technique, which combines weak quadrupole illumination and an attenuated phase- shifting mask, has been developed. 0.03 micrometers lithography with i-line can be performed with this technique. It is also confirmed that KrF excimer laser lithography is a powerful candidate for generating 0.18 micrometers -rule devices.
