Last week, the second largest chip foundry GlobalFoundriesAnnounceEnd 7 nanometer manufacturing process development, focusing on the existing 14nm/12nm process (14LPP/12LP). CTO Gary Patton insists that the company made this decision not because of technical issues, but after careful consideration of the business opportunities and financial issues of the 7-nm process.


This decision prompted AMD to hand over all 7nm CPU and GPU orders to TSMC. Gary Patton is interviewed by IEEE SpectrumWhy give up 7 nanometer process development. He said that he is willing to challenge cutting-edge technology as a CTO, but for employees, customers and shareholders, their company must have a sustainable and profitable business. It is clear that the development of cutting-edge technology will continue to erode the return on investment. There are very few customers who need a 7-nanometer process, and the cost of research and development is rising while demand is falling. So they ended up choosing to focus on existing technology to get the best return on investment. He believes that 14LPP/12LP still has a lot of room for improvement, and the resources needed to improve the existing technology are much less than the development of 7 nm or even 5 nm. He believes that even by 2022, three-quarters of the chip market still only needs 12 nanometers.
