▎ 摘　　要

NOVELTY - The contact includes: a first layer comprising a conductor; a second layer comprising a second conductor or a semiconductor; and a barrier layer comprising graphene. The barrier layer separates the first layer and the second layer. USE - Contact of electronic package, such as semiconductor device (claimed). ADVANTAGE - Contacts with the graphene barrier layer display enhanced reliability as the graphene layer inhibits diffusion and reaction between the layers contacting the barrier layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method to prepare a contact of a semiconductor device. DESCRIPTION OF DRAWING(S) - The drawing shows microscopy images of the top surfaces of a gold/nickel/silicon contact and a gold/graphene/nickel/silicon contact after annealing at 500, 600 or 700 degrees Celsius.
