摘  要:信息社会的迅猛发展极大推动了对高性能计算的需求。而先进互补金属氧化物半导体(CMOS)制造工艺是制造高性能计算芯片的保障,因此成为世界顶尖设计公司和芯片制造企业竞争的技术高地。文章概述了鳍式场效应晶体管(FinFET)之后技术演进到环栅场效应晶体管(GAAFET)的必然性,以及在工艺模块、系统集成和工艺无损表征上带来的挑战。在先进CMOS制造工艺技术的创新上,需要有从器件开发到系统设计的思维转变;设计工艺协同优化(DTCO)将会发挥越来越重要的作用。面向未来国产先进的CMOS制造工艺的发展,在技术开发和人才培养方面提出了发展建议和举措。The rapid development of information society has greatly promoted the demand for high-performance computing(HPC),and advanced complementary metal oxide semi-conductor(CMOS)technology ensures the manufacturing of HPC chips.As a result,the technology has been pursued vigorously by top chip design companies and chip manufacturing enterprises in the world.This paper reviews the necessity of a Fin field-effect transistor(FinFET)evolving into a gate-all-around field-effect transistor(GAAFET)and analyzes challenges in technological modules,system integration,and non-destructive technological characterization.It is pointed out that the innovation of advanced CMOS technology requires a transition from device development to system design,and design technology co-optimization(DTCO)will become increasingly important.In addition,the paper puts forward suggestions and measures for the development of advanced CMOS technology in China in terms of technology development and talent cultivation.
