摘要：

We demonstrate the smallest FinFET SRAM cell size of 0.063 mu m(2) reported to date using optical lithography. The cell is fabricated with contacted gate pitch (CPP) scaled to 80 nm and fin pitch scaled to 40 nm for the first time using a state-of-the-art 300 mm tool set. A unique patterning scheme featuring double-expose, double-etch (DE2) sidewall image transfer (SIT) process is used for fin formation. This scheme also forms differential fin pitch in the SRAM cells, where epitaxial films are used to merge only the tight pitch devices. The epitaxial films are also used for conformal doping of the devices, which reduces the external resistance significantly. Other features include gate-first metal gate stacks and transistors with 25 nm gate lengths with excellent short channel control.
