Abstract
The dry etching process by using NLD (Neutral Loop Discharge Plasma) has been evaluated. The loading effect was measured applying the CAR (Chemically Amplified Resist) negative resist process in the low pressure etching condition, where an excellent CD (Critical Dimension) uniformity was obtained.
