Abridging CMOS Technology.

Area of Science:

• Semiconductor device physics
• Materials science
• Microelectronics engineering

Background:

• The continuous miniaturization of silicon-based complementary metal-oxide-semiconductor (CMOS) devices, a cornerstone of modern electronics, is facing fundamental limitations.
• Challenges span device physics, fabrication complexities, and economic viability, signaling an end to traditional scaling approaches.

Discussion:

• Exploring novel materials beyond silicon, such as 2D materials or novel III-V compounds, is crucial for next-generation integrated circuits.
• Investigating alternative device architectures, like gate-all-around (GAA) transistors or vertical field-effect transistors (VFETs), is essential to overcome scaling roadblocks.

Key Insights:

• The intrinsic properties of silicon limit further device scaling due to quantum effects and increased variability.
• Fabrication processes for sub-nanometer nodes are becoming prohibitively complex and expensive.
• The economic feasibility of continuing the historical scaling trend is diminishing rapidly.

Outlook:

• Future semiconductor technology will likely rely on heterogeneous integration of diverse materials and advanced 3D architectures.
• Research into novel electronic materials and device designs is critical for sustained progress in computing power and energy efficiency.
• The industry must shift focus from pure scaling to innovative solutions addressing performance, power, and cost.
