Lithographic performance of thin dendritic polymer resists

A dendritic polymer resin lithographic resist is evaluated for surface and line edge roughness, and feasibility to enter the manufacturing environment. This novel resin demonstrates superb surface smoothness; linewidth variation is 5.1 A and surface roughness is 12.9 A. Most of the key concerns in the manufacturing environment are adequate, if not excellent. This resist shows excellent potential for processes where very small and smooth features are required, such as gate level definition.
