A 7nm CMOS platform technology featuring 4th generation FinFET transistors with a 0.027um2 high density 6-T SRAM cell for mobile SoC applications

For the first time, a leading edge 7nm CMOS platform technology for mobile SoC applications is presented. This technology provides >3.3X routed gate density and 35%∼40% speed gain or >65% power reduction over our 16nm FinFET technology. A fully functional 256Mb SRAM test-chip with the smallest high density SRAM cell of 0.027um
²
is demonstrated down to 0.5V. The 4
^th
generation FinFET transistors are optimized with device mismatch reduction by 25%∼35% and multi-Vt device options to enable low power and high performance design requirements.
