Abstract
Sub-100nm patterns have been fabricated in thick PMMA film on thick silicon substrates at low beam voltages using commercial e-beam machines. A higher contrast and an improved resolution are obtained by using an IPA development. 50-100nm lines are fabricated in 0.5- 1.0μm PMMA film on silicon substrates with 20-25kV e-beams. Practical aspects of sub-100nm pattern fabrication have been estimated. Pattern accuracy, field butting error, and overlay accuracy are better than ±0.1 μm 3 sigma.
