2025年,半导体行业正式叩响GAA时代。 随着GAAFET 技术的落地,"逻辑芯片下一个大趋势" 的光环也随之褪去。 三星在3nm中已应用GAAFET技术,台积电也表示今年下半年大规模生产的2nm芯片中将应用GAAFET技术。 那么 GAA 之后,谁来接棒?按此前的技术路径,CFET 本是下一代架构的公认标杆。但随着 VLSI 2025 的启幕,中国北京大学提出的 FlipFET 技术,引 起更大轰动。 GAA之后,谁来接棒? 五十多年来,半导体行业一直依赖于一个简单的公式:缩小晶体管尺寸,将更多晶体管封装到每个晶圆上,然后看着性能飙升,成本骤降。 在 2D 晶体管时代,FinFET是扛大旗者。 在此之前是MOSFET,不过当栅极长度逼近20nm门槛时,对电流的控制能力急剧下降,漏电率也在升高,传统的平面MOSFET正式走到尽头。 | | MOSFET | FinFET | GAAFET | | | --- | --- | --- | --- | --- | | 名称 | 绝缘栅型场效应晶体管 | 鳍式场效应晶体管 | 环绕栅极场效应晶体管 | 多桥通道场效应晶体管 | | | | | (GAAFET) | ...

芯片,要变了!
半导体行业观察· 2025-07-25 01:44
Core Viewpoint - The semiconductor industry is transitioning from traditional scaling methods to a new paradigm called CMOS 2.0, which focuses on 3D integration and vertical stacking of components to overcome the limitations of 2D scaling and maintain performance improvements [2][3][34]. Group 1: CMOS 2.0 Overview - CMOS 2.0 aims to break the limitations of single-chip designs by manufacturing each layer independently and optimizing them for their specific functions before stacking them into a unified component [5][10]. - The approach combines four main concepts: backside power delivery, fine-pitch hybrid bonding, complementary FETs (CFET), and a dual-sided process [6][8][9]. Group 2: Technical Pillars of CMOS 2.0 - Backside power delivery moves power rails to the wafer's backside, reducing voltage drop and freeing up routing resources [12]. - Fine-pitch hybrid bonding connects stacked layers using dense copper-to-copper contacts, allowing for high bandwidth and low latency interconnects [12]. - CFET technology vertically stacks n-type and p-type transistors, reducing standard cell height by 30% to 40% and improving density without shortening gate lengths [13]. - The dual-sided process allows for device and contact construction on both sides of the wafer, creating new wiring and integration options [12]. Group 3: Design Rule Changes - CMOS 2.0 fundamentally alters how designers think about system-on-chip (SoC) partitioning, wiring, and verification, requiring early decisions on module placement and current flow [16]. - The design process must adapt to a three-dimensional approach, necessitating new tools for modeling and managing power delivery and signal integrity across multiple layers [17]. Group 4: Manufacturing Challenges - The transition to CMOS 2.0 faces significant manufacturing challenges, particularly in achieving sub-micron hybrid bonding and managing wafer thinning and backside processing [19][20]. - The complexity of integrating multiple technologies into a single process flow poses risks to yield management and process control [19]. Group 5: Economic Considerations - CMOS 2.0 presents potential reliability and cost risks, as any defect in one layer can compromise the entire stack, necessitating rigorous online testing and monitoring [24]. - The economic viability of 3D wafer stacking may vary across markets, with high-performance computing being more likely to absorb the associated costs compared to other sectors [25]. Group 6: Competitive Alternatives - CMOS 2.0 is not the only strategy for scaling; alternatives like 2.5D integration using chiplets and monolithic CFET scaling are also being explored, each with its own advantages and challenges [26][28]. - The choice among these strategies will depend on product requirements, economic constraints, and the readiness of the ecosystem [30]. Group 7: Future Outlook - The success of CMOS 2.0 as a standard platform hinges on overcoming its technical, economic, and logistical challenges, with a focus on achieving reliable, void-free interconnects and mature EDA processes [32][33]. - High-performance computing, AI accelerators, and premium mobile devices are expected to be the initial applications for CMOS 2.0 technology, with broader market adoption possible as yield and process stability improve [34].
