Intel pronounces cancellation of 20A course of node for Arrow Lake, goes with exterior nodes as a substitute, possible TSMC [Updated]

In a shock transfer, Intel announced at this time that it now not plans to make use of its personal ‘Intel 20A’ course of node with its upcoming Arrow Lake processors for the patron market. As an alternative, it should use exterior nodes, possible from accomplice TSMC, for all of Arrow Lake’s chip elements. Intel’s solely manufacturing tasks for the Arrow Lake processors can be packaging the externally manufactured chiplets into the ultimate processor. Intel CFO Dave Zinsser additionally commented on the matter throughout the firm’s dialogue on the Citi International TMT Convention at this time, indicating the corporate would ‘skip over productizing’ the 20A node to cut back capital expenditures and spending. Intel tasks it should save half a billion {dollars} by skipping the 20A node.

The announcement comes as Intel embarks on an unlimited restructuring within the wake of troubling monetary outcomes final quarter. The corporate continues to lay off 15,000 workers, among the many largest workforce reductions in its 56-year historical past.

The node change comes after Intel initially demoed a wafer of Arrow Lake processors fabbed on the 20A node at its Innovation 2023 occasion, which indicated the chips have been already far alongside within the improvement cycle. On the time, Intel mentioned Arrow Lake would come to market in 2024. Since then, trade rumors pointed to the 20A node solely getting used for a subset of the Arrow Lake family, whereas the rest would use a TSMC node. Now it’s clear that not one of the merchandise will use the 20A node.

Intel says its essential next-gen ‘Intel 18A’ node stays on observe for launch in 2025. It has now shifted its engineering assets from 20A to the newer 18A node, which the corporate says was spurred by the energy of the yield metrics for 18A. Intel again noted that it had reached a sub-0.40 D0 defect density (def/cm^2) for 18A, a vital measurement of the yield price for a course of node. A course of node is often thought-about production-worthy and wholesome as soon as D0 reaches 0.5 or beneath.

Intel will now leapfrog over its 20A course of solely and keep away from the capital expenditures required to deliver the node to full manufacturing. Eliminating the always-eye-watering ramp prices of a brand new node, significantly one as superior as 20A, will certainly contribute to the corporate assembly its cost-cutting targets – Intel says the transfer will save half a billion {dollars}.

The Intel 20A node was by no means deliberate for a lot of merchandise as a result of firm’s fast-track transfer to the extra superior 18A node because it races to satisfy its objective of delivering 5 nodes in 4 years, so constructing out an in depth 20A manufacturing would have restricted returns. Nevertheless, Intel’s 20A served as a car for a number of new advances, like RibbonFet Gate-All-Around (GAA) know-how, which is Intel’s first new transistor design since FinFET arrived in 2011. It additionally marked the debut of the corporate’s PowerVia backside power delivery tech, which routes energy for the transistors by means of the bottom of the processor die.

Intel says the learnings it gained from its 20A node have contributed to the success of its 18A node, which is smart provided that 18A is a tighter refinement of the applied sciences invented for 20A. Naturally, there can be hypothesis that Intel encountered yield points with its 20A node, however we aren’t conscious of any exterior indicators of the well being of the 20A course of node.

Intel notes that it has chips constructed with the 18A course of already powered on within the lab and booting working programs and in addition touted that it has now delivered its vital PDK 1.0 to clients. This key design framework will enable exterior clients to construct chips utilizing Intel course of nodes, a vital part of Intel’s IDM 2.0 turnaround plan, which hinges on the corporate turning into an exterior foundry producing chips for exterior clients.

Microsoft and the U.S. Department of Defense have already signed on to supply chips utilizing the 18A node, and Intel plans to have eight tape-ins by the center of 2025.
