SemiAnalysis Teardown Shows Intel 18A Matches TSMC N3E but Lags in Density

SemiAnalysis’s teardown of Intel’s Panther Lake processor confirms the first commercial use of the 18A process, featuring RibbonFET transistors and PowerVia backside power delivery. While 18A achieves logic density comparable to TSMC’s N3E, it does not surpass TSMC’s newer N2 or Samsung’s SF2 nodes. The chip uses a multi-tile design, with compute on 18A but graphics and I/O on TSMC nodes, highlighting a mixed manufacturing strategy.

Intel Shifts Nova Lake Tile Production In-House Amid 18A Yield Gains

Intel is reportedly moving the majority of Nova Lake's compute-tile production in-house, shifting from an initial plan to dual-source with TSMC on the 2 nm N2 node to an 80-90% in-house plan on the 18A node. The uptick in 18A yields—defect rates around 0.1-0.2 and fewer delays—lets Intel scale internal production. Current capacity is about 30,000 wafers per month across Fab 52 (Phoenix) and Hillsboro, enough for Panther Lake but likely needing more capacity for Nova Lake before its consumer launch.
