Abstract
An MLG (multilayer graphene) device layer structure is connected with a via. The structure includes an M1 MLG interconnect device layer upon a dielectric layer. Interlayer dielectric isolates the M1 MLG interconnect device layer. An M2 MLG interconnect device layer is upon the interlayer dielectric. A metal via penetrates through the M2 MLG interconnect device layer, the interlayer dielectric and the M1 MLG interconnect device layer and makes edge contact throughout the thickness of both M1 MLG and M2 MLG layers. A method diffuses carbon from a solid phase graphene precursor through a catalyst layer to deposit MLG on a dielectric or metal layer via application of mechanical pressure at a diffusion temperature to form MLG layers.
