Future Scopes of Nanochips

This paper presents a comprehensive overview of the scopes of nanochips - ultra-miniaturised integrated circuits based on nanotechnology - covering their enabling technologies, fabrication methods, application domains, performance advantages, and the multidisciplinary challenges that shape their future. We analyse recent trends in device scaling, materials (2D materials, nanowires, quantum dots), architecture (neuromorphic, quantum accelerators), and system-level implications (power, reliability, security). The paper includes a comparative table of nanochip metrics, illustrative graphs showing projected scaling trends, and conceptual figures that map applications to industry sectors. Our findings show that nanochips promise dramatic improvements in compute density and energy efficiency across edge devices, biomedical implants, and AI accelerators, while raising new fabrication, testing, and security challenges. Finally, we present research directions to bridge laboratory demonstrations and practical deployment.
