Interconnects

Definition

Interconnects refer to the conductive pathways that connect various components within electronic devices, enabling communication and power distribution. In nanoelectronics, these interconnections are crucial because they facilitate the integration of nanoscale components, which can significantly enhance the performance and functionality of devices. As technology progresses, the need for smaller, more efficient interconnects becomes increasingly important to meet the demands of modern electronic applications.

5 Must Know Facts For Your Next Test
