Intel Faces Yield Problems in Key 18A Manufacturing Process for Next PC Chip

Intel’s ambitious push to regain leadership in high-end chip manufacturing has hit a significant hurdle. According to sources familiar with the matter, its next-generation “18A” production process — critical for the upcoming “Panther Lake” laptop chips — is struggling with low yields, raising concerns about profitability and competitiveness against industry leader TSMC.

The 18A process is central to Intel’s strategy of expanding its in-house chipmaking and building a competitive foundry business. Billions have been invested in factories and technology, aiming to close the gap with TSMC. Panther Lake, expected in high volumes in 2025, features next-gen transistors and a more efficient power delivery system.

However, early tests have shown disappointing results. Only a small fraction of chips have met required standards, with yields reportedly around 5% late last year and about 10% by mid-2024. Intel disputes these figures but has not disclosed official numbers. Industry norms suggest profitability usually requires yields between 70% and 80%. Without major improvements by the planned Q4 launch, Intel may face selling chips at reduced margins or even at a loss.

Intel CFO David Zinsner acknowledged yields “start off low and improve over time” and stressed that the product remains “fully on track.” Still, sources describe the 18A rollout as risky, likening it to a “Hail Mary” due to the simultaneous introduction of multiple untested technologies.

Compounding the challenge, defect rates per chip area are reportedly about three times higher than acceptable for mass production. While Intel is working to improve yields monthly, margins are not yet favorable even at current levels. The company has warned that without securing external business for 14A — the successor to 18A — it could exit advanced manufacturing altogether.

For now, Intel still relies partly on TSMC for some in-house designs. Its follow-up to Panther Lake, “Nova Lake,” is also expected to be produced partly by TSMC.
