Abstract

This work demonstrates the first successful integration of monolayer MoS2 nanosheet FET in a gate-all-around configuration. At a gate length of 40nm, the transistor exhibits a remarkable mathrm{I}-{ mathrm{ON}} sim 410 mu mathrm{A}/ { mu} mathrm{m} at mathrm{V}-{ mathrm{DS}}=1 mathrm{V}, achieved with a monolayer channel, '0.7 nm thin. The FET has a large mathrm{I}-{ mathrm{ON}}/ mathrm{I}-{ mathrm{OFF}} gt 1 mathrm{E}8, positive mathrm{V}-{ mathrm{TH}} sim 1.4 mathrm{V} with nearly zero DIBL. Higher drive current can be achieved through stacking of multiple channel layers. We propose here a fully integrated flow and we detail the feasibility of the most critical modules: stack/channel preparation, fin patterning, inner spacer, channel release, contact. The successful demonstration of MoS2 NS with high performance and of the stacked NS modules further clarifies the value proposition in 2D materials for transistor scaling.
