Abstract

반도체소자 제조공정에서, 프리-실리사이드세정을 할때, HF용액세정후, 수산화암모늄용액으로 다시 세정을 함으로써, HF세정시 웨이퍼표면에 부착되는 미세한 오염물질을 제거하여 반도체수율을 향상시킬 수 있다.In the semiconductor device manufacturing process, when pre-silicide cleaning, after washing the HF solution, and washed again with ammonium hydroxide solution, it is possible to remove the fine contaminants attached to the wafer surface during HF cleaning to improve the semiconductor yield.
