These trends have fueled major advancements in semiconductor technology, with 2D NAND transitioning to 3D NAND over the last decade. The 3D transition has also begun in logic, with FinFET technology giving way to gate-all-around (GAA) transistors and complementary field-effect transistor (CFET) architecture offering attractive benefits. Many are also expecting DRAM to follow in the future. However, scaling semiconductors in the "3D era" is immensely difficult. Chipmakers contend with rising levels of complexity at every new node and are challenged to increase transistor density while reducing power consumption.
Continued advancement in fabrication methods and technologies will be essential to enable and further scale the next generation of GAA transistors, DRAM architectures and 3D NAND devices that today contain over 200 layers. To sustainably create chips with nanoscale-level precision and the right cost structure, wafer fabrication equipment (WFE) makers like Lam Research will need to push the boundaries of plasma physics, materials engineering and data science to deliver the equipment solutions needed. Harnessing the power of data is proving to be a game-changer in delivering these capabilities into production. We are collecting richer data from our equipment and using more advanced data science techniques to convert that into repeatable processing of millions of wafers.
As the industry tackles the challenges of the 3D era, here are five potential trends to watch.
Multi-function process chambers will bring etch and dep even closer together for high-volume production
