2D materials: from memory entry to logic’s future
Two-dimensional (2D) materials were once regarded as important candidates for extending semiconductor scaling. Because they are only an atom thick, they are theoretically very suitable for fabricating extremely small, ultra-low-power transistors. However, once these ideas move into advanced logic processes, challenges begin to surface. The problem lies in the fact that using 2D materials to fabricate FETs requires process control that is nearly at the single-atom level.
