Author(s): Integration of nano-scale materials in microcircuits: Challenges and opportunities
Abstract: The integration of nanoscale materials into microcircuit architectures represents a pivotal advancement in next-generation electronics, enabling enhanced performance, reduced power consumption, and greater functional diversity. This research investigates the integration of graphene, Carbon Nanotube (CNT) arrays, and Transition Metal Dichalcogenides (TMDs) such as MoS₂ and WS₂ with conventional silicon-based platforms. Advanced fabrication techniques including precise alignment, clean interface preparation, and optimized metallization were employed to address critical challenges of compatibility, defect control, and scalability. Material characterization through Raman spectroscopy and AFM confirmed low defect densities and acceptable surface roughness, particularly for graphene and CNT arrays. Electrical measurements revealed that graphene and CNTs achieved superior carrier mobilities, while TMDs exhibited high on/off ratios, highlighting their complementary roles in heterogeneous integration. Contact resistance was minimized using palladium contacts, and annealing significantly improved mobility and interface stability. Statistical analysis further identified alignment tolerance as a key factor influencing functional yield, demonstrating a strong linear correlation between precision and integration success. Reliability testing confirmed device stability under thermal cycling and electrical stress. These results support the hypothesis that precise interface engineering and controlled process parameters can enable reliable and scalable nano-micro integration. The study concludes with practical recommendations emphasizing hybrid material architectures, contact engineering strategies, process optimization, and standardized metrology for future large-scale adoption.
