Is SMIC N+3’s Metal Pitch Smaller Than Intel 18A?
Text
SemiAnalysis, a technology research firm, has reported that SMIC’s N+3 manufacturing process features a smaller metal pitch than Intel’s 18A process, according to internal data reviewed by the outlet. The finding highlights a potential shift in the competitive dynamics of semiconductor manufacturing, as metal pitch is a critical factor in determining chip performance and density.

Technical Details of the Metal Pitch Comparison
The metal pitch refers to the distance between adjacent metal interconnects on a chip, with smaller pitches enabling higher transistor density and faster signal transmission. SemiAnalysis cited internal documents from SMIC indicating that the N+3 process achieves a metal pitch of 16 nanometers (nm), while Intel’s 18A process, announced in 2023, reportedly has a metal pitch of 18 nm. The data suggests SMIC has closed a gap in advanced node production, though the firm noted that independent verification of these figures remains pending.

Industry Implications and Competitive Context
The comparison comes amid heightened competition between Chinese chipmaker SMIC and U.S.-based Intel, which has faced delays in its 18A node development. Intel’s 18A process, part of its “Arrow Lake” roadmap, was originally slated for 2024 but has seen repeated postponements, according to industry analysts. SMIC’s N+3, a successor to its N+2 process, is positioned as a key offering for 5G, AI, and high-performance computing applications.
SemiAnalysis highlighted that smaller metal pitches are typically associated with more advanced manufacturing capabilities, but cautioned that other factors—such as yield rates, power efficiency, and design complexity—also influence a node’s overall performance. The firm noted that SMIC’s N+3 is still in early production phases, and its full capabilities may not yet match those of mature nodes like TSMC’s 3nm or Intel’s 18A.

Sources and Verification Challenges
The reported metal pitch measurements for SMIC and Intel were derived from internal technical briefings and third-party analysis, according to SemiAnalysis. However, the firm acknowledged that direct comparisons between competing processes are inherently complex due to differences in measurement methodologies and proprietary data.
Intel has not publicly commented on the specific metal pitch figures cited by SemiAnalysis, while SMIC has not independently confirmed the data. Industry observers emphasized that such claims should be treated as preliminary until validated by independent testing or official announcements.

What Comes Next for Semiconductor Manufacturing
The potential for SMIC to match or exceed Intel’s metal pitch specifications underscores the rapid pace of innovation in the semiconductor industry. Analysts at Gartner noted that advancements in interconnect technology are critical for sustaining Moore’s Law, as traditional scaling methods face physical and economic limits.
SemiAnalysis recommended that investors and industry stakeholders closely monitor the commercialization of SMIC’s N+3 process, particularly its adoption in high-volume applications. The firm also called for greater transparency from both SMIC and Intel to clarify the technical specifications of their respective nodes.

Broader Industry Trends and Future Outlook
The semiconductor industry is currently navigating a period of intense competition, with companies like TSMC, Samsung, and Intel vying for leadership in next-generation manufacturing. SMIC’s progress with the N+3 process aligns with its strategy to reduce reliance on foreign technology and capture market share in China’s growing tech sector.
Recent reports suggest that SMIC has secured contracts with domestic clients for N+3-based chips, though the scale of production remains limited. Meanwhile, Intel has shifted focus to its 14A and 10A nodes, which are expected to precede the 18A process. Analysts at Bernstein Research noted that Intel’s delayed 18A timeline could create opportunities for competitors to gain market traction.
