Abstract
We present a comparison of line edge roughness on wet and dry etched reticles manufactured at the same mask shop. These measurements were taken on a Leica LWM250, and compare identical features on both masks. A 30% improvement in line edge quality was seen on the dry etched plates. Data supporting these results is presented.
