Novel etching techniques, such as the use of pulse-time-modulated plasma and a selective radical generation method ('radical injection method'), have been developed. The pulse-time-modulated plasma makes possible highly selective, high-rate, and charge-up-damage-free etching. And the new radical injection method using nonperfluorocarbon gases (CF3I and C2F4) in high-density plasma enables polymerization and etching rate to be controlled independently through the selective generation of CF2 and CF3 radicals in the plasma.
