TSMC Struggling to meet 3nm Demand
TSMC is facing challenges in meeting Apple's demand for 3-nm chips, as the company encounters difficulties with tools and yield, hindering the progress towards large-scale production. TSMC and Samsung, the main competitors in the foundry industry, are in a race to achieve the first 3-nm production for clients like Apple and Nvidia in high-performance computing and smartphones. Nevertheless, both companies are encountering obstacles during this transition period.
TSMC has plans to begin production of Apple's A17 and M3 processors using the N3 node in the latter half of 2023, while also focusing on ASIC-based server CPUs at N4 and N3. The introduction and ramp-up of 3 nm technology has faced delays as TSMC needed to incorporate EUV lithography through ASML, its tool supplier. The high cost of EUV multi-patterning has affected the cost-effectiveness of EUV, leading to efforts to minimize the number of EUV multi-patterning layers. This, however, has resulted in larger die sizes. The scaling of the "real" 3-nm node will likely occur once a higher-throughput EUV system is available, which is expected in the second half of 2023. TSMC is also witnessing a shortage of talent for its 3nm chip production which is only compounding the issue.
Technical Issues with 3nm Chips for Samsung
Similar to TSMC, Samsung is also encountering challenges in recruiting talent for its 3nm chip production and related R&D activities. In late 2022, Samsung faced a substantial setback with its 3nm GAA chips, experiencing a low yield rate of only 20%, causing the loss of key customers like Qualcomm during the initial phase. However, the yield rate for its next-generation chips has improved to around 60-70%, comparable to TSMC, which may help regain lost customers. While it's unlikely for those facing production issues with TSMC to shift to Samsung, the intensifying competition in the race for 3nm production will have a positive impact on the future of this technology.
However, all this slowdown of 3nm production will also lead to issues with 2nm production timelines. Currently TSMC and Samsung both expect to start production of 2nm chipsets in 2025. However, it still remains to be seen if these issues will lead to delays in 2nm timelines as well. While challenges and delays in production timelines are inevitable, the industry's commitment to pushing the boundaries of semiconductor technology remains unwavering. The advancements in 3nm and 2nm processes will not only cater to the demands of consumer electronics but also propel innovation in diverse sectors, including healthcare, automotive, telecommunications, and more.
3nm and 2nm Roadmap and Transition
The transition to 3nm and 2nm process nodes will bring about significant improvements in power consumption, enabling more energy-efficient devices. With the continued growth of portable electronics, Internet of Things (IoT) devices, and electric vehicles, the demand for power-efficient chips is paramount. The smaller transistor sizes and innovative design techniques employed in these advanced nodes will contribute to longer battery life and reduced energy consumption, enhancing the user experience and driving sustainability.
Furthermore, the 3nm and 2nm process nodes will facilitate the integration of more complex functionalities within a smaller chip footprint. This will enable the development of highly integrated systems-on-chip (SoCs) with improved performance and functionality. The increased transistor density and advanced packaging technologies will pave the way for sophisticated applications such as artificial intelligence (AI), machine learning, virtual reality (VR), and augmented reality (AR), transforming industries and enabling new possibilities.
In addition, the 2nm process node is expected to bring notable advancements over its 3nm predecessor. The smaller transistor sizes will result in faster switching speeds, lower leakage currents, and higher transistor density, further enhancing performance and power efficiency. This opens up opportunities for even more compact and powerful devices, paving the way for novel applications in areas like edge computing, autonomous vehicles, and advanced robotics.
What the Future will mean for 3nm and 2nm Process Nodes
The future of the 3nm and 2nm process holds immense potential for the semiconductor industry, unlocking new horizons in performance, power efficiency, and miniaturization. As leading foundries like TSMC and Samsung navigate the challenges and complexities associated with these advanced nodes, they are laying the foundation for the next generation of high-performance chips.
As the semiconductor industry continues to evolve, it is expected that 3nm and 2nm process nodes will mark significant milestones in chip manufacturing. These advanced nodes will empower the development of cutting-edge technologies, fueling further digital transformation and shaping the future of computing. With each successive node, the industry will inch closer to the theoretical limits of miniaturization, paving the way for a new era of high-performance, energy-efficient, and technologically advanced devices that will shape our world for years to come.
