Title : Can a simple iTFET become a mainstream of future technology generation
Abstract:
In this presentation, we embark on a journey to explore the transformative potential of a simple yet innovative inductive Tunnel Field-Effect Transistor (iTFET), contemplating its possible ascent to a leading role in shaping future technology landscapes. The narrative traverses the realms of simplicity, cost-efficiency, power frugality, multifunctionality, streamlined fabrication, production scalability, and its distinctive attributes. As we set the stage, it is imperative to address the inherent limitations of conventional Gated PIN TFETs. These devices grapple with the vexing issues of gate-bias dependent subthreshold swing (SS) degradation, anemic current drive, substantial leakage current, ambipolar complexities, and the formidable challenge of Trap Assisted Tunneling (TAT). The iTFET, poised as a novel protagonist in this tale, emerges as a harbinger of novel solutions to circumvent these prevailing obstacles. The iTFET's relevance assumes paramount importance when viewed against the backdrop of mainstream CMOS technology's limitations. The industry's pursuit of achieving a subthreshold swing below thermal constraints faces substantial impediments, particularly in applications necessitating ultra-low-power paradigms, such as high-performance yet power-savvy IoT and AI systems. While Tunnel Field-Effect Transistors (TFETs) have tantalized with their promise, their adoption trajectory encounters formidable challenges rooted in manufacturing intricacies, the quest for performance augmentation, and the unwavering quest for reliability.
At the heart of our exploration lies the conundrum of Trap Assisted Tunneling (TAT), a thorn in the side of TFET feasibility. TAT's adverse impact compounds the already challenging endeavor of achieving subthreshold swings smaller than the elusive 60mV threshold. This pivotal challenge reverberates across the industry, influencing transistor switching efficiency and practical real-world implementation. It is precisely this challenge that we aim to dissect and potentially overcome during our discourse. The iTFET, our central protagonist, shines as a beacon of hope and ingenuity. It heralds a paradigm shift in semiconductor device architecture. Unlike conventional MOSFETs, which operate predominantly as majority carrier Gated NPN or PNP devices, TFETs, including iTFET, function as minority carrier tunneling Gated PIN diodes but in a reverse-biased configuration. This departure from convention opens vistas of opportunity for enhanced performance and resilience. Remarkably, the fabrication processes for the iTFET are fully compatible with those of recent CMOS technologies, ensuring seamless integration into contemporary semiconductor manufacturing landscapes. Adding to its allure, the iTFET flaunts an impressively facile fabrication process. Its manufacturing journey is marked by simplicity, efficiency, and a significantly reduced wafer footprint. Notably, its current drive is not tethered to the conventional W/L ratio but is instead directly proportional to the product of channel length (L) and width (W), a distinctive attribute that sets it apart from its predecessors. In summary, this presentation endeavors to illuminate the transformative potential of iTFET technology. It does not merely rest on the promise of overcoming current semiconductor device shortcomings but holds the potential to redefine the very foundations of mainstream technology generation. The iTFET's attributes of simplicity, cost-effectiveness, power efficiency, multifunctionality, ease of fabrication, and scalability, combined with its unique current drive characteristics, make it a compelling candidate for shaping the future of semiconductor technology.
