CMOS technology brings to society services, machines and tools that deliver more and more functions to the benefit of their user. The economic driving force demands that device density on the chip should continuously increase. Making transistors smaller is the easiest way to achieve this scaling, but there is a limit beyond which lateral scaling will no longer be possible.

Why not switch to volume scaling?

Today, we have entered a power-limited era. Information and communication technologies now account for up to 10% of the total electrical energy generated in industrialized countries. Power consumption at the device level must be reduced for the benefit of the end user. Tweaking up the speed of electrons using new semiconductors would help.

Why not switch to materials scaling?

The concept behind COMPOSE3 exploits materials scaling as well as device stacking as a new approach to density scaling.
