Device and process of forming device with device structure formed in trench and graphene layer formed thereover

摘要

A graphene-based device is formed with a substrate having a trench therein, a device structure on the substrate and within the trench, a graphene layer over the device structure, and a protective layer over the graphene layer. Fabrication techniques include forming a trench in a substrate, forming a device structure within the trench, forming a graphene layer over the device structure, and forming a protective layer over the graphene layer.
