Abstract
Multi-level resist systems are rapidly becoming essential in the drive towards submicron lithography. Such systems offer many inherent advantages over single level schemes, such as planarization of underlying substrate, higher resolution and formation of high aspect ratio patterns. Other advantages, particular to specific exposure technologies, can also be found. These include minimization of backscatter and proximity effects for electron beam lithography or reduction of standing wave effects and depth of focus problems for photolithography.
