這些i-line步進(jìn)器具有與尼康DUV掃描儀相同的縮小率和視場大小,是曝光次臨界層的理想選擇,這些層大約占設(shè)備20層或更多層的一半。這些特性與高產(chǎn)量相結(jié)合,提供了成本性能和生產(chǎn)力的組合,有助于降低資本成本。
NSR-SF120的設(shè)計方式類似于掃描型KrF步進(jìn)器NSR-S204B、NSR-S205C和NSR-S206D,以及ArF步進(jìn)器NSR-S305B和NSR-S306C。新開發(fā)的高數(shù)值孔徑鏡頭使i-line分辨率飛躍至280 nm。該系統(tǒng)可以有效地暴露次臨界層以支持130-100 nm設(shè)備節(jié)點,同時為300 mm時代提供高吞吐量。
