Beyond Si-Based CMOS Devices: Needs, Opportunities, and Challenges

Information processing is being driven by CMOS’s dimensional and functional scaling1.technology into an ever-expanding range of fresh applications. These applications have been made possible by scaling thanks to improvements in complexity and performance. In order to increase the historical cadence of integrated circuit scaling as dimensional scaling of CMOS inevitably approaches fundamental constraints, a number of pioneering and advancement of signal processing devices and microarchitectures for both present and innovative functions are ongoing. That has flashed attention in processing and storage devices, as well as new heterogeneous integration technologies and system architectural paradigms. As a result, this chapter emphasizes an international roadmap of device and systems (IRDS) viewpoint with advanced research of devices and provides a connection between existing classical CMOS and the field of nano-electronics once CMOS scaling is achieved. The main objective of proposed chapter is to explore, evaluate, and scale practical developing facilities and new architectural approaches in terms of their long-term potential and scientific maturity, as well as to identify logical and technical issues preventing the semiconductor industry from accepting them as having an acceptable level of risk of future development. Additionally, this chapter examines “Beyond CMOS devices” for applications that go beyond Moore, such as hardware security.
