Qualcomm and some other companies are leaving money on the table because they can't get enough 28-nm chips to meet demand out of foundry TSMC. That has driven companies into the arms of other foundries but could it also prompt a return the customer-funded joint venture fab designed to guarantee IC supplies for the backers?
Qualcomm and some other companies are leaving money on the table because they can't get enough 28-nm chips to meet demand out of foundry partner Taiwan Semiconductor Manufacturing Co. Ltd. Horror of horrors some customers are looking for ways to switch other companies' chips into slots previously designed around those vendors' ICs.
Could this be one of the ways Intel gets a leg up in the smartphone and tablet computer markets? Whether or not that happens to any significant degree, the current undersupply situation looks set to trigger refinements to some business models.
But that does not mean the immediate end of the foundry-fabless model that has served and driven the electronics industry for the last couple of decades. More likely it will stimulate a return to a strategy tried before: the funded joint-venture wafer fab. But this time with the additional wrinkle that process R&D will be front and center of the collaboration.
Those with sufficiently long memories will remember that Altera Corp., Analog Devices Inc. and Integrated Silicon Solutions Inc. each took stakes in a joint venture wafer fab back in the mid-1990s. That joint venture was controlled by TSMC and was used by the fabless participants to try and ensure their future supply of chips after a period of undersupply and allocation.
A $1.2 billion leading-edge 200-mm wafer fab was built in Camas, Washington, and became Wafertech. The fact that Wafertech is now a wholly-owned subsidiary of TSMC, illustrates that the story did not go particularly smoothly for all concerned. Altera committed about $140 million to gain an 18 percent share in the joint venture but by the time the plant was up and running the market was in oversupply again. In 1997 TSMC announced it would cut prices due to excessive capacity and fierce competition. So some might say Altera put its money down to no great effect on that occasion.
So why would Qualcomm, or indeed Altera, do the same again now?
I wonder if circumstances are really as different today from what they were in the last joint venture backed fab episode?
Companies have been going fabless to begin with because *building* fabs is so enormously expensive that very few companies can afford to do it on their own, and it's likely a few that could simply see better returns on investment elsewhere. Joint ventures are fraught with inherent difficulties because of the issues of getting agreement from the partners on what is being done, what each is expected to put into it, and what each will get out of it, and *maintaining* that agreement as changes in the underlying economy require adjustments to the plans.
If I'm Qualcomm, I'm leaving money on the table because I can't get all the chips I want, but how *much* money is that? How much will it cost to build this joint venture fab? How long will it take me to recoup my investment? And what happens when the wheel turns as it always does and we move to a condition of oversupply again?
I may look at the numbers, and decide I'm better off *leaving* money on the table, because the amount of potential revenue I'm forgoing won't approach what it would cost me to build a fab, even with partners, to address capacity issues that are ultimately transitory.
I think that now is a good time to be an IDM. The fabless chip companies can't have it both ways. I agree with others that it is too late for them to catch Intel by the 14 nm node anyway. This problem of constrained capacity at the leading edge could go away in a couple of quarters between improving yields and more capacity coming on line. I don't think that now is the time to go back to a failed model - like committing to a JV if you are Qualcomm. I think there is more downside risk than upside potential there.
I think ultimately that Qualcomm and other chip companies would just as soon continue to outsource the whole enchilada to TSMC and others, rather than get in bed with TSMC in a JV. As you point out, Peter, owning a fab, or owning it in part, is not simply a matter of opening up a magic chip-building facility. There is a lot of work and know how that has to be done in terms of process development. All of that would have to come from TSMC or another foundry. In the end, it wouldn't be that much different from the situation that Qualcomm and others enjoy today--they pay money to foundries, the foundries provide the knowledge, capability and capacity to build their chips. Entering a JV would only mean that a fabless company was on the hook for the depreciation of the facility and equipment, which would be a liability as soon as oversupply conditions took hold. And oversupply is never that far off.
Not only that, but Qualcomm and its fabless brethen today enjoy the right to work with different foundries, play them off each other, and negotiate the best deal. Once they are a partner in the fab, that flexibility goes out the window.
Of course the advantage of such an arrangement, on the surface, would appear to be certainty of supply. Right about now, that sounds great. But as Qualcomm executives acknowledged the other day, at least part of the problem with the 28-nm capacity crunch is that demand for Qualcomm's 28-nm chips is simply greater than the company anticipated. If Qualcomm had been able to accurately predict what the demand would be, TSMC would have had the capacity available, I think.
For the last decade or so our Fabless Wonders have had a free ride on process R&D done at "credible" IDMs ( in my book after their HKMG fiasco IBM no longer qualifies ) siphoned out through various consortia and tool vendors.
They may now have $$$ on the table but they can't buy time. Intel started finFET work almost 8 years back. Hard to catch up even at 14 nm within 5 years even if the fabless wonders were now able to pry off enough process talent on behalf of their Foundries and went at it using the traditional chinese water torture approach to Physics ( a huge no. of experiments over a wide parameter space rather than targeting on narrow space with the benefit of device simulation ).
