Rumor: TSMC Won’t Build New Capacity for Intel, Views Orders as Temporary

Intel’s final decision to tap pure-participate in foundries like TSMC for perhaps any long run venture has sent shockwaves by way of the marketplace. A person of the largest thoughts lifted in the wake of the announcement is just how momentary it really is. Intel is definitely positioning the hold off as a pragmatic subject of having its property in purchase, and for now, TSMC would seem to agree.

In accordance to DigiTimes, TSMC has no programs to extend its fab capacity for Intel, viewing it as a momentary consumer instead than a very long-phrase acquire. If you’re a enthusiast of Intel manufacturing (or would like to be again), this is a quite fantastic sign. When Intel is not one particular of the five most significant semiconductor manufacturers any for a longer period, all of which are capable of about 1,000,000 wafer begins for each month, it is even now one particular of the most significant at an approximated 817,000 wafer begins for each month. And compared with TSMC, Samsung, or GlobalFoundries, Intel makes use of its individual capacity nearly entirely for its individual products.

Additional complicating the problem is the point that Intel manufacturers the vast majority of its products on its leading-edge nodes, even though pure-participate in foundry wafer begins will be spread across all of the nodes the foundry manufacturers, not concentrated in 1-2 processes. In short, the capacity hole involving Intel and any foundry Intel needed to tap to manage its manufacturing is likely to be big. TSMC is mentioned to at present check out alone as Intel’s “rescuer,” not its very long-phrase manufacturing associate.

Intel Could Be Snared by the Exact same Entice That At the time Caught AMD

Prior to AMD and Intel settled their antitrust lawsuit, AMD was underneath a significantly much more restrictive x86 license than it at present holds nowadays. A person of these constraints was the necessity to individual its individual fabs. AMD was not permitted to shell out TSMC, UMC, or any other pure-participate in foundry to manufacture x86 CPUs. It experienced to use its individual amenities. Intel, of system, is underneath no these restriction, but there’s a variation of this difficulty haunting the semiconductor phase however.

Intel’s foundries are explicitly optimized to develop Intel x86 CPUs, and its CPU styles are intended for fabrication at its individual foundries. This hand-in-glove engineering is the advantage of getting an built-in system producer (IDM), and it is one particular of the good reasons Intel employed to give to explain its marketplace-leading functionality. So very long as Intel is building and filling its individual fabs, this product operates effectively. Shifting enterprise to a various foundry, having said that, creates difficulties.

The point that Intel’s fabs are so specialized means they principally have worth to Intel. Each individual greenback that Intel invests in paying TSMC to apply a specialized product or service line is a greenback it is not investing in repairing its individual fabrication technological know-how. Each individual facility that TSMC delivers on the internet for Intel to use is a facility it’ll probably want to use for a little something else as before long as Intel can return to its individual fabs.

What takes place if Intel simply cannot return to its individual fabs? This does not truly resolve just about anything in the close to phrase. TSMC does not have the capacity to soak up Intel’s entire enterprise for the reason that 1). Intel’s enterprise is massive, 2). Fabs take 3-5 several years to develop. Even if Intel needed to dump all of its individual manufacturing nowadays and TSMC actively needed to take about as Intel’s producer, it would take several years to provide up new factories or modify current Intel fabs to satisfy TSMC’s new tips.

I wrote the other working day that Intel experienced specified alone a 24-36 month deadline to resolve its manufacturing, but upon additional reflection, I’m not certain that was the most precise way to summarize the difficulty. Intel simply cannot afford to pay for to hold out 24-36 months to start off generating programs to transfer its manufacturing to TSMC or Samsung. Supplied the issues and complexity of these transitions, Intel would want to be generating an announcement much more like this:

“We intend to deploy our individual Xnm node and will changeover to TSMC for Ynm beginning in 2022 / 2023.”

It would seem unlikely just about anything a lot less would suffice. Intel’s foundry associate would want the assurance of a publicly introduced roadmap and would want the lead time to either develop or allocate capacity. Intel, in change, would have an obligation to advise its buyers and to create programs for how it would dispose of its foundry enterprise. Building on n-nanometer at Intel and n+1 at TSMC would also smooth the roadmap instead than forcing Intel into additional delays.

Supplied these information, I’d modify my individual earlier statement. The point that Intel is even now committing to a late 2022 – early 2023 timeline for its 7nm CPUs shortens the window the organization has to pull the trigger on a creation improve. Should really it choose to shift to TSMC or Samsung, it would want to make that announcement inside of the upcoming 12-18 months to prevent the likelihood of even greater delays. The provide-up time on new fabs is very long adequate that Intel would nearly unquestionably want to either license a course of action node, shell out TSMC immediately to develop a fab, or operate its fabs in tandem with TSMC to prevent intense creation shortages.

I even now assume it is much more likely that Intel deploys its individual 7nm node and moves ahead with its initiatives to overtake the pure-participate in foundries and re-build course of action management than that the organization pulls the plug on its individual IDM status. The timeline for generating that final decision just may be a little shorter than I originally implied.
