IMEC: Chips Scale to 0.2nm by 2046

🔑 Enhanced Key Takeaways

• •IMEC's roadmap relies heavily on the transition to Forksheet and CFET (Complementary FET) architectures to maintain area scaling beyond the 2nm node.
• •The 0.2nm nomenclature refers to 'effective' scaling rather than physical gate length, as physical dimensions are approaching atomic limits where quantum tunneling dominates.
• •The roadmap emphasizes 'system-technology co-optimization' (STCO), shifting focus from pure transistor density to optimizing the entire chip architecture and packaging to gain performance.

🛠️ Technical Deep Dive

• •Transition from FinFET to Gate-All-Around (GAA) nanosheets is the immediate precursor to advanced nodes.
• •Implementation of CFET (Complementary FET) stacks n-type and p-type transistors vertically to reduce footprint by approximately 50%.
• •Utilization of high-NA EUV (Extreme Ultraviolet) lithography is essential for patterning features at the sub-2nm level.
• •Integration of backside power delivery networks (BSPDN) to decouple power and signal routing, reducing IR drop and improving performance.
