This rapid evolution is not merely incremental; it represents a fundamental shift in how chips are designed and fabricated. With major foundries aggressively targeting 2nm and sub-2nm nodes, the industry is witnessing a "More than Moore" paradigm, where innovation extends beyond traditional transistor scaling to encompass novel materials and advanced integration methods. The implications are profound, impacting everything from the smartphones in our pockets to the vast data centers powering AI, setting the stage for a new era of technological capability.
Engineering Marvels: The Core of Semiconductor Advancement
The heart of this revolution lies in several key technical advancements that are redefining the fabrication process. At the forefront is the aggressive transition to 2nm and sub-2nm process nodes. Companies like Samsung (KRX: 005930) are on track to mass produce their 2nm mobile chips (SF2) in 2025, with further plans for 1.4nm by 2027. Intel (NASDAQ: INTC) aims for process performance leadership by early 2025 with its Intel 18A node, building on its 20A node which introduced groundbreaking technologies. TSMC (NYSE: TSM) is also targeting 2025 for its 2nm (N2) process, which will be its first to utilize Gate-All-Around (GAA) nanosheet transistors. These nodes promise significant improvements in transistor density, speed, and power efficiency, crucial for demanding applications.
Central to these advanced nodes is the adoption of Gate-All-Around (GAA) transistors, which are now replacing the long-standing FinFET architecture. GAA nanosheets offer superior electrostatic control over the transistor channel, leading to reduced leakage currents, faster switching speeds, and better power management. This shift is critical for overcoming the physical limitations of FinFETs at smaller geometries. The GAA transistor market is experiencing substantial growth, projected to reach over $10 billion by 2032, driven by demand for energy-efficient semiconductors in AI and 5G.
Equally transformative is the deployment of High-NA EUV lithography. This next-generation lithography technology, primarily from ASML (AMS: ASML), is essential for patterning features at resolutions below 8nm, which is beyond the capability of current EUV machines. Intel was an early adopter, receiving ASML's TWINSCAN EXE:5000 modules in late 2023 for R&D, with the more advanced EXE:5200 model expected in Q2 2025. Samsung and TSMC are also slated to install their first High-NA EUV systems for R&D in late 2024 to early 2025, aiming for commercial implementation by 2027. While these tools are incredibly expensive (up to $380 million each) and present new manufacturing challenges due to their smaller imaging field, they are indispensable for sub-2nm scaling.
Another game-changing innovation is Backside Power Delivery (BPD), exemplified by Intel's PowerVia technology. BPD relocates the power delivery network from the frontside to the backside of the silicon wafer. This significantly reduces IR drop (voltage loss) by up to 30%, lowers electrical noise, and frees up valuable routing space on the frontside for signal lines, leading to substantial gains in power efficiency, performance, and design flexibility. Intel is pioneering BPD with its 20A and 18A nodes, while TSMC plans to introduce its Super Power Rail technology for HPC at its A16 node by 2026, and Samsung aims to apply BPD to its SF2Z process by 2027.
Finally, advanced packaging continues its rapid evolution as a crucial "More than Moore" scaling strategy. As traditional transistor scaling becomes more challenging, advanced packaging techniques like multi-directional expansion of flip-chip, fan-out, and 3D stacked platforms are gaining prominence. TSMC's CoWoS (chip-on-wafer-on-substrate) 2.5D advanced packaging capacity is projected to double from 35,000 wafers per month (wpm) in 2024 to 70,000 wpm in 2025, driven by the surging demand for AI-enabled devices.
