Intel "Panther Lake" Hits 80% Yield on 18A Node

Intel's latest "Panther Lake" SoC, featuring a compute tile built on the company's 18A node, has reportedly achieved an 80% yield. This is great news for Intel Foundry, as the 18A yields have been steadily improving. The "Panther Lake" compute die measures approximately 8.004 x 14.288 mm, resulting in a silicon area of 114.304 mm². With this design, yields are around 80%, indicating not only low defect rates for the node but also a high parametric yield, meaning a significant number of dies have all functioning elements. This suggests that Intel is overcoming its historic parametric yield problems alongside manufacturing challenges.

A testament to this progress might be the recently rumored shift in "Nova Lake" production. Intel plans to produce the majority of "Nova Lake" compute tiles in-house, with about 80-90% being manufactured by Intel Foundry and the remainder by TSMC, as part of a dual-sourcing strategy. For a mature node like 18A, defect rates are now low, around D0=0.1 or D0=0.2. It is likely that Intel has achieved the lower end of this range due to advancements in the node and months of high-volume production with "Panther Lake." Combined with the relatively small compute tile used in this SoC, parametric yields appear to be strong. Read full story
