In this paper, for the first time we demonstrate that horizontally stacked gate-all-around (GAA) Nanosheet structure is a good candidate for the replacement of FinFET at the 5nm technology node and beyond. It offers increased Weff per active footprint and better performance compared to FinFET, and with a less complex patterning strategy, leveraging EUV lithography. Good electrostatics are reported...
We present a 7nm technology with the tightest contacted poly pitch (CPP) of 44/48nm and metallization pitch of 36nm ever reported in FinFET technology. To overcome optical lithography limits, Extreme Ultraviolet Lithography (EUV) has been introduced for multiple critical levels for the first time. Dual strained channels have been also implemented to enhance mobility for high performance applications.
We demonstrate a process flow for creating gate-all-around (GAA) Si nanowire (SiNW) MOSFETs with minimal deviation from conventional replacement metal gate (RMG) finFET technology as used in high-volume manufacturing. Using this technique, we demonstrate the highest DC performance shown for GAA SiNW MOSFETs at sub-100 nm gate pitch, and functional high-speed ring oscillators.
Strain engineering has been in the heart of CMOS technology for over a decade. However, the effectiveness of conventional strain elements, such as stress liners, embedded S/D stressors, and stress memorization, is significantly reduced when device gate pitch is scaled below 100 nm as needed for 14nm node and beyond. Substrate strain engineering, where the channel itself is formed out of a strained...
