Abstract
A Cu/HSQ damascene structure can be achieved by a new HSQ patterning technology using a TiN mask and post-CMP cleaning with electrolytic ionized ultra-pure cathode water. A Cu/HSQ structure with capacitance 17% lower than that of HSQ patterned by a conventional photo-resist-mask process was successfully fabricated with a sufficiently small number of post-Cu-CMP particles, only 30% of that with conventional post-Cu-CMP cleaning.
