▎ 摘　　要

NOVELTY - The method involves providing a copper substrate. A nickel metal layer is deposited on the copper substrate. A mask layer is formed on the nickel metal layer. The mask layer is provided with multiple openings arranged in array. A copper-nickel alloy region is formed with a copper-nickel alloy region. A graphene layer is formed on a flat surface. A set of electrodes is formed on a graphene region. A ratio of an area of the graphene region and an area of another graphene region is between 1/5-1/3. A ratio of a total area of the electrodes and the total area of the graphene regions is between 1/3 and 1/2. USE - Embedded graphene diode manufacturing method. ADVANTAGE - The breakdown voltage of a diode is improved. A current density of a first electrode and a second electrode is ensured to be close to or a same, so as to prevent a breakdown caused by a current is not uniform. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of an embedded graphene diode manufacturing method.
