GlobalFoundries on Monday announced an important strategy shift. The contract maker of semiconductors decided to cease development of bleeding edge manufacturing technologies and stop all work on its 7LP (7 nm) fabrication processes, which will not be used for any client. Instead, the company will focus on specialized process technologies for clients in emerging high-growth markets. These technologies will initially be based on the company’s 14LPP/12LP platform and will include RF, embedded memory, and low power features. Because of the strategy shift, GF will cut 5% of its staff as well as renegotiate its WSA and IP-related deals with AMD and IBM. In a bid to understand more what is going on, we sat down with Gary Patton, CTO of GlobalFoundries.

7LP Canned Due to Strategy Shift

GlobalFoundries was on track to tape out its clients’ first chips made using its 7 nm process technology in the fourth quarter of this year, but “a few weeks ago” the company decided to take a drastic, strategic turn, says Gary Patton. The CTO stressed that the decision was made not based on technical issues that the company faced, but on a careful consideration of business opportunities the company had with its 7LP platform as well as financial concerns.

It is noteworthy that when GlobalFoundries first announced its 7LP platform in September 2016, it said that it would start risk production of processors using this technology in early 2018 (PR), which means that the first chips should have been taped out before that. When the company detailed the process in June 2018, it said that it expected to start “volume production ramping in the second half of 2018” (PR), which would be close to impossible if customers taped out their first chips only in Q4.

Generally, it looks like the company had to adjust its roadmap somewhere along the way, moving the start of high-volume manufacturing (HVM) further into 2019. Whether or not these adjustments had any implications on GlobalFoundries is up to debate. Keep in mind that AMD’s first 7 nm product was designed for TSMC’s CLN7FF from the beginning, so the company did not bet on GF’s 7LP in late 2018 anyway, and no rush with the manufacturing technology was needed for GF’s key customer.

Along with the cancellation of the 7LP, GlobalFoundries essentially canned all pathfinding and research operations for 5 nm and 3 nm nodes. The company will continue to work with the IBM Research Alliance (in Albany, NY) until the end of this year, but GlobalFoundries is not sure it makes sense to invest in R&D for ‘bleeding edge’ nodes given that it does not plan to use them any time soon. The manufacturer will continue to cooperate with IMEC, which works on a broader set of technologies that will be useful for GF’s upcoming specialized fabrication processes, but obviously it will refocus its priorities there as well (more on GF’s future process technologies later in this article).

So, the key takeaway here is that while the 7LP platform was a bit behind TSMC’s CLN7FF when it comes to HVM – and GlobalFoundries has never been first to market with leading edge bulk manufacturing technologies anyway – there were no issues with the fabrication process itself. Rather there were deeper economic reasons behind the decision.

Economic Reasons Behind the Move

As we noted in our article covering GlobalFoundries's new CEO hire earlier this year, former CEO Sanjay Jha was never able to make the company profitable. His key tasks were to increase GlobalFoundries’s sales, streamline the company in general, and ensure that it executes its roadmap.

To address the needs of the manufacturer’s traditional key client (AMD) and ensure that his company was competitive against other contract makers of semiconductors, he licensed Samsung Foundry's 14LPP fabrication technology. That strategy worked well. With Sunjay Jha at the helm, GlobalFoundries has managed to land a variety of new customers and increase its sales of semiconductor wafers from approximately $4.121 billion in 2013 to $6.176 billion in 2017. Besides, the foundry’s leading-edge Fab 8, which has been processing wafers using exclusively 14LPP process technology for well over 1.5 years now, is running at full capacity.

To ensure that GlobalFoundries remains competitive against Samsung Foundry and TSMC in the long run, Sunjay Jha obtained IP and development teams from IBM (along with two fabs and a lot of obligations), and poured in billions of dollars in development of the 7LP fabrication technology platform. The latter would include three generations of manufacturing processes and, possibly, a custom high-performance technology available exclusively to IBM. While everything appeared to proceed smoothly with the 1st Gen 7 nm process (DUV only), the 2nd Gen 7 nm process (with EUV used for non-critical layers, such as padding) still needed some additional development investments, and the 3rd Gen 7 nm (with intensive usage of EUV) required even more money for development and further could require installation of additional EUV equipment. Meanwhile, there were two things to consider.

First. If GlobalFoundries kicks off production using the 1st Gen 7 nm fabrication process, it would have needed to cure all of its teething troubles and offer its clients a roadmap forward. The latter would have included 2nd Gen and 3rd Gen 7 nm, but nothing stops there. Customers would have asked for 5 nm and then for 3 nm nodes. Meanwhile, you cannot tell your clients that you are packing up after a certain node and then hope that this node will be a success (the same is true for DUV-only 1st Gen 7 nm).

Second. Development of leading-edge process technologies is extremely expensive. Every new node requires billions of dollars in investments. Those costs are eventually amortized over each chip the company makes, so to keep increasing R&D costs from driving up chip prices, foundries need to produce more chips. To make more chips, they need to either run multiple fabs that use the same process technology (these are going to cost $10+ billion in the EUV era), or build giant fabs that process a gargantuan number of wafers (these are going to cost $20+ billion in the EUV era). Meanwhile, GlobalFoundries has only one leading-edge fab featuring capacity of 60,000 wafer starts per month. As a result, either GlobalFoundries has to pass these R&D costs on to the finite number of wafers it processes – and become uncompetitive against rivals in the process – or eat the costs with reduced profitability.

Meanwhile, having spent well over $20 billion on GlobalFoundries over the last 10 years, Mubadala, the owner of the company, is not inclined to lose more money or invest tens of billions in the hopes of becoming profitable one day. The investor wants GlobalFoundries to stop bleeding and start generating profits.

“The culture of [our investments], the ones I’ve been involved with, was about accumulating assets and then just maintaining it,” said Mubadala CEO Khaldoon Al Mubarak in an interview with Bloomberg earlier this year. “The shift that has happened over the last couple of years, that I’ve tried to push at Mubadala today, is a monetization strategy that makes sense, not with a view to cash out but with a view to reinvest.”

Gary Patton admits that GlobalFoundries never planned to be a leading producer of 7-nm chips in terms of volume. Furthermore, the company has been seeing increasing adoption of its 14LPP/12LP technologies by designers of various emerging devices, keeping Fab 8 busy and leaving fewer step-and-scan systems for 7LP products.

Without another big fab, it would be impossible to make any new leading-edge process technology competitive against Samsung and TSMC due to aforementioned scale reasons. Meanwhile, building a new fab (or even expanding the Fab 8 with another clean room module, which is something that GF considered several years ago) and creating another node or two would require another $10 – $15 billion from Mubadala, which is not inclined to invest just now. As a result, the GlobalFoundries has decided to switch entirely to specialized process technologies for emerging high-growth markets. This strategic shift enables it to reduce spending on R&D, slowdown procurement of new equipment, reduce its workforce by 5% (most of which will be in Malta), and potentially avoid direct competition against the aforementioned contract makers of semiconductors.

    GF has suffered since the beginning from the luck of good leadership. The actual CEO and his team had no vision at all. how did they invest billions on 7nm and then they find out they have no capacity to manufacture 7nm devices even if the production was ready. Wasted over $500 millions on EUV tools that now GF will sell back to ASML for penny on a dollar. GF management was playing with the house money (Mubadala), When Mubadala said enough is enough...the party is over. Malta site will shutdown in 2 years max when AMD move 100% to 7nm at TSMC and stop ordering 14nm products. Reply
  • GF Milking UAE - Friday, September 21, 2018 - link

    A GF EVP I worked with overseas years earlier asked if I would look at their brand new FAB 8 = very disappointing at best. They tried to hire me after my assessment of FAB 8 (6+ years ago). I met with CEO & CFO, FAB 8 (ex-AMD) Manager, FAB 8 (ex-GE) HR Director, personality profiling, 80 emails, etc. and finally got an offer 3 months later which I turned down the next day. I saw no opportunity for a successful money making operation, no profit sharing, no IPO, just a pay check and politics. Way to many people having influence without any accountability for the companies success. Some of these people have been milking the UAE for 10 years. Too many losers milking the UAE investors that could careless if the company ever made a profit. Instead of purging these milk UAE for a paycheck people, GF promoted these people like the HR director. History = UAE (ATI) buys AMD (cannot compete in a 2 horse race). Then buys Chartered (company that lost money for Singapore Gov for 20+ years) I worked next door to Chartered for 7 years watching Chartered never make profit while the gov financed more fabs. Then the straw that broke the camels back GF gets paid a Billion+ Dollars to take over money losing IBM. Next put a bunch of money losing IBM people in charge of making a profit. Promote ex-IBMer to CEO and now the camels back if finally broken after 10 years of losers padding their pockets with oil money. What ever happened to building that FAB in UAE to employee the people at home??? UAE still has the $$$$$$$$$$$$ to listen to BS = break up and sell off the assets for the least loss. Nothing like paying people to convince you to Buy High and Sell Low so you will lose less of your countries money. Chinese have a saying the Cow who drinks its own milk will not thrive. UAE should have told everyone in management you have 3 years to make a profit or your terminated (period), especially the original FAB 8 HR Director. Reply
