2D Semiconductors
Novel semiconductor materials of atomic-scale thickness, with transition metal dichalcogenides as the primary representatives. These materials exhibit favorable electrical properties and natural bandgaps, and are considered a key technological pathway for sustaining chip performance improvements in the post-Moore era.
Timeline (last 90 days)
Two-dimensional semiconductors, due to their atomic-scale thickness and superior electrical properties, are seen as potential candidates for extending Moore's Law and breaking through power consumption and size bottlenecks.
To date, no manufacturer has achieved wafer-level mass production of two-dimensional semiconductors.
The mass-production bottlenecks for 2D semiconductors are concentrated at three levels: thin-film growth processes (with CVD as the mainstream approach), thermal budget compatibility with back-end-of-line (BEOL) interconnect processes, and contact resistance issues.
Obtaining uniform, low-defect monolayer 2D thin films on 300mm large-diameter wafers remains a challenge.
