Abstract:
1. A graphene interconnection comprising: a substrate having a major surface; a first insulating film provided above the major surface of the substrate, and including an interconnection trench; a first catalyst film formed on the first insulating film on both side surfaces of the interconnection trench; a first graphene layer formed on the first catalyst film on the both side surfaces of the interconnection trench, and the first graphene layer including graphene sheets stacked in a direction non-parallel to the both side surfaces, wherein the graphene sheets are on the both side surfaces of the interconnection trench; and a first contact plug electrically connected to the first graphene layer, wherein opposing end portions of at least one of the graphene sheets that is on the both side surfaces of the interconnection trench is directly in contact with the first contact plug and a second contact plug, respectively.
