Abstract

A FinFET technology named 22FFL has been developed that combines high-performance, ultra-low power logic and RF transistors as well as single-pattern backend flow for the first time. High performance transistors exhibit 57%/87% higher NMOS/PMOS drive current compared to the previously reported 22nm technology [1]. New ultra-low power logic devices are introduced that reduce bit cell leakage by 28x compared to a regular SRAM cell enabling a new 6T low-leakage SRAM with bit cell leakage of sub 1pA/cell. An RF device with optimized layout has been developed and shows excellent fT/fMAX of (230GHz/284GHz) and (238GHz/242GHz) for NMOS and PMOS respectively.

22FFL:一种用于移动和射频应用的高性能超低功耗FinFET技术
一种名为22FFL的FinFET技术首次将高性能、超低功耗逻辑和射频晶体管以及单模式后端流结合在一起。与之前报道的22nm技术相比,高性能晶体管的NMOS/PMOS驱动电流提高了57%/87%[1]。引入了新的超低功耗逻辑器件,与常规SRAM单元相比,将位单元泄漏减少了28倍,实现了新的6T低泄漏SRAM,位单元泄漏低于1pA/单元。设计了一种优化布局的射频器件,其fT/fMAX分别为NMOS (230GHz/284GHz)和PMOS (238GHz/242GHz)。
