      Abstract:

      A review. Generation-three (Gen-3) immersion lithog. can be an   enabler for the 32 nm half-pitch node. For Gen-3 lithog. to be   successful, however, there must be three major breakthroughs in   materials development: high refractive index ("high-index")   lenses, high-index immersion fluids, and high-index photoresists.   Currently a material for a high-index lens element, lutetium   aluminum garnet (LuAG), has been identified. However, suitable   materials choices remain elusive for both the Gen-3 fluid and   resist. This paper reviews the successes and failures in the   search for Gen-3 high-index materials.
