Tecnologias em sistemas de circuitos integrados

Abstract

The crescent semiconductor market aims more and more researches at it’s main technology, CMOS (Complementary metal-oxide-semiconductor). This paper is a literature review based on the databases IEEE and Science Direct. The Moore’s Law is presented and its end is questioned. Also, the consequences that limit CMOS transistors scaling are discussed, which would be approximately 20 nm for the gate length. Lastly, new technologies that have a potential to overcome CMOS technologies, as the CNTFET (Carbon nanotube field-effect transistor) and SpinFET (Spin field-effect transistor), are presented.
