Intel's 14A Process Defect Density Drops Faster Than Expected, CFO Compares to 22nm
Key points
- 14A defect density is dropping faster than Intel's targets.
- Intel CFO compared 14A's defect reduction to the 22nm process.
- Risk production for 14A is set for late 2027, HVM in 2028.
- 14A will use second-gen RibbonFET and PowerDirect technologies.
Improved Defect Density for 14A
Intel's 14A (1.4nm-class) fabrication process is demonstrating a faster rate of defect density reduction than initially projected. According to Intel CFO David Zinsner, the current defect density trajectory for 14A is tracking better than the company's internal targets and surpasses the defect reduction rates observed in previous nodes.
Comparison to 22nm Process
Zinsner noted that the performance in defect reduction for 14A is comparable to Intel's 22nm technology, which he described as one of Intel's most successful nodes. This comparison refers to the rate of defect reduction at a similar stage of development, approximately two years before mass production.
Future Production Timeline
Intel plans to commence risk production of its own products using the 14A process in the second half of 2027. High-volume manufacturing for 14A is scheduled to begin in 2028. External customers are reportedly inquiring about potential 14A volumes.
Technological Advancements
The 14A process will incorporate advanced technologies, including second-generation gate-all-around (GAA) RibbonFET transistors and second-generation backside power delivery, named PowerDirect. It will also be compatible with High-NA EUV lithography for complex patterning.
Contextual Considerations
While the defect density reduction is positive, it is important to note that current defect density metrics and definitions may differ from those used for the 22nm process 16 years ago due to advancements in wafer processing and inspection equipment. Defect density also does not directly equate to product yield.
