Paper Abstract

We investigated dry-develop resist as the top layer in a bilayer system. The resist consisted of polyacetylene with silicon atoms, PTMDSO (poly 4,4,7,74etramethyl-4,7-disila- 2-octyne) as a base polymer, and a phenyl azide as a photosensitive addition agent. 0.30 pm line and space negative patterns were resolved, when the resist exposed using a KrF excimer laser stepper system was developed in the down stream of 02/CF4 plasma. The sensitivity was around 100 mJ/cm2 and the oxygen plasma resistance was about 50 times greater than that of novolak resist.
